The effect of branded versus standardized e-cigarette packaging and device designs: an experimental study of youth interest in vaping products.

OBJECTIVES: Standardized ('plain') packaging is effective in reducing the appeal of cigarettes among young people. This study examined the impact of plain packaging and brand imagery on interest in trying e-cigarettes among youth. STUDY DESIGN: Experimental design. METHODS: Two online experiments were conducted in February 2020 as part of the ITC Youth Tobacco & Vaping Survey, conducted with 13,624 16- to 19-year-olds in Canada, England, and the USA. In the between-group Experiment 1, participants were randomized to view a set of 3 e-cigarette brands, in either their original external packaging ('branded' condition) or standardized olive-green packaging ('standardized' condition), and asked to select the product they would be most interested in trying. The within-group Experiment 2 examined brand imagery directly on devices, including potential differences in appeal among subgroups. Each participant viewed 4 pod-style e-cigarette devices: one 'plain' and 3 in colourful 'skins'. Logistic regression models were conducted to test the effect of condition, adjusting for demographics, smoking and vaping status. RESULTS: In Experiment 1, participants in the 'standardized' packaging condition were significantly more likely to indicate 'I have no interest in trying any of these products' (72.3%) than those in the 'branded' condition (66.9%, AOR 1.45, 95% CI 1.33-1.59). Experiment 2 results indicated differences in e-cigarette appeal by sex in the selection of male- and female-oriented designs, and by cannabis use for a Rastafarian-themed design. CONCLUSIONS: Brand imagery on e-cigarettes can target products to specific subgroups. Removal of imagery, in the form of standardized packaging, has the potential to reduce interest in trying e-cigarettes among young people.

Appeal rating and visual attention associated with youth-appealing cannabis packaging: An eye-tracking experiment.

BACKGROUND: Cannabis-infused edibles have grown in popularity particularly among young people in the United States. Youth-appealing cannabis packaging is common and associated with concerns on its public health impacts. This study aims to assess associations of youth-appealing cannabis edible package attributes with appeal ratings and visual attention of young adults. METHODS: Seventy-two young adults participated in an eye-tracking experiment, in which each participant viewed seven randomly ordered cannabis edible package images with varying youth-appealing attributes, including a cartoon character, a young adult model, bubble font, berry flavor, and gummy bear shape. Two primary outcomes were assessed: 1) appeal ratings elicited on a scale from 0 to 10 based on self-reporting, and 2) fixation durations on predefined areas of interest in the package images based on eye-tracking data. Multivariate linear regressions were conducted to assess associations. RESULTS: Packages containing a cartoon character, bubble font, berry flavor, or gummy bear shape received higher appeal ratings than the package with no youth-appealing attributes. Youth-appealing attributes received longer fixation durations than non-youth-appealing attributes. The presence of any youth-appealing attribute is associated with reduced fixation durations on the warning label, with the largest reduction in the package with multiple youth-appealing attributes. CONCLUSIONS: Youth-appealing attributes on cannabis edible packages are associated with higher appeal ratings, more visual attention towards those attributes, and less visual attention towards warning labels among young adults in the United States. Regulations banning youth-appealing attributes may be effective in reducing appeal of cannabis edibles and increasing attention towards warning labels.

Graphic health warnings and plain packaging in the Philippines: results of online and household surveys.

In line with Article 11 of the WHO Framework Convention on Tobacco Control, the Philippines has implemented graphic health warnings on cigarette packs. To date, there has been no published literature evaluating the perceived effectiveness of GHWs in the Philippines. This study aims to contribute to the evidence on the perceived effects of graphic health warnings (GHWs) in cigarette packaging and the potential impact of plain packaging in the Philippines. The study involved an online convenience survey and a nationwide household survey. Mock-up sets of cigarette packs based on the Philippines' law on GHWs, and Thailand's and Singapore's plain packaging were shown to respondents to rate their attractiveness, quality, taste, cost, social appeal, appeal to youth, noticeability, appeal to non-smokers, attempt to quit, ease of quitting, discouraging smoking, and perceived harm to health on a five-point Lickert scale. The online and household surveys recruited 2,701 respondents in total. Online and household survey respondents considered plain packaging with larger graphic health warnings and visible quitlines from Thailand and Singapore to be more effective in discouraging them from smoking. Both sets of survey respondents also found mock-ups from Thailand and Singapore more motivating for them to attempt quitting than cigarette pack mock-ups from the Philippines. The study concludes that current graphic health warnings in the Philippines are ineffective in instilling health consciousness among Filipinos. Policymakers should consider larger graphic health warnings and plain packaging of cigarettes to motivate smokers to quit and discourage Filipinos from smoking.

New Zealand adolescents' responses to plain packaging and new pictorial warning labels: Repeat cross-sectional survey analysis.

OBJECTIVE: This article aims to examine the impact on adolescents of New Zealand's 2018 legislation introducing plain (standardised) packaging and enhanced pictorial warning labels (PWLs). METHODS: Data came from Year 10 (14-15 years old) students in the 2016 (2,884 participants) and 2018 (2,689 participants) Youth Insights Surveys conducted 2 years before and immediately after legislation implementation. We used binary and ordinal logistic regression to investigate changes in brand awareness and preference, brand and pack appeal, and PWL salience and impact. RESULTS: The proportion of all participants, and ever, ex/experimental and current smokers who could name one or five tobacco product brands decreased in 2018. There was a modest and nonstatistically significant decrease in the proportion of current smokers citing brand name and image, and a larger decrease in the proportion stating perceived harm to health, influenced preferred brand choice. Having a preferred brand among current smokers and pack appeal, and PWL salience and impact among ex/experimental and current smokers were largely unchanged. CONCLUSIONS: We found preliminary evidence that plain packaging and enhanced PWLs reduced tobacco brand awareness and salience, and misperceptions about tobacco brand harmfulness. Data collection occurred shortly after implementation. Additional studies are required to assess longer term impacts of these interventions. PUBLIC HEALTH IMPLICATIONS: The findings complement existing evidence documenting the impact of plain packaging and PWLs on adolescents. Given limitations due to the proximity of the 2018 survey to legislation implementation, further studies with longer follow-up are required.

Perceptions of plain packaging and health warnings among university students in Turkey: a survey-based experiment.

BACKGROUND: Cigarette pack design plays a crucial role in attracting customers, especially when other marketing methods are limited by policy. University students who engage in casual smoking take the risk of developing an addiction. The objective of this study was to assess the effects of plain packaging (PP) and graphic health warnings (GHWs) on cigarette packages on three outcome variables (negative affect, avoidant responses, and intentions to quit) among ever-smoker university students in Ankara, Turkey, where youth smoking prevalence is high. METHODS: An online survey-based experiment was used to collect data. The respondents were randomly assigned to one of the five conditions that contained images of cigarette packs with specific design elements. Regression analyses (n = 623) were used to compare across conditions and to estimate the effects of combined warnings (versus text-only warnings), stronger GHWs (versus old GHWs), and PP (versus branded packages) on the outcome variables, accounting for potential confounders. RESULTS: Stronger GHWs generated more negative affect (0.31 points out of 5, p = 0.010) and avoidant responses (0.42 points out of 5, p = 0.002) than old warnings (when brand logos were visible). Plain packages generated more negative affect (0.48 points out of 5, p < 0.001) and avoidant responses (0.46 points out of 5, p = 0.001) than branded packages (with old warnings). Disentangling the effects of PP and new GHWs revealed that neither had individual differential effect on intentions to quit within 6 months. CONCLUSIONS: Although no differential effect of PP or harsher GHWs was found on intentions to quit when respondents were exposed to images on screen, both design elements were found to be effective in generating negative affect and avoidant responses. More work is needed to design effective tobacco control measures among youth during critical years of tertiary education.

Colours, capsules and concept flavour names on cigarette packs appeal to youth in Mexico.

BACKGROUND: Flavoured cigarettes are popular in Mexico. We examined how cigarette packaging design features used to communicate flavour influence perceptions of appeal, harm, perceived interest and pack preference among Mexico City residents. METHODS: We conducted an experimental survey. Participants aged 13-34 years were randomly assigned to one of three conditions, viewed packs with systematically manipulated design features (colour, capsule image and flavour name) and answered questions on appeal, perceived harm, perceived interest and pack preference. Data were analysed using mixed effects and conditional logistic regression. RESULTS: 1500 adolescents and 950 adults participated. Regardless of flavour, cigarette packs with a background colour and capsule image were more appealing to adolescents (OR=13.19, 95% CI 11.53 to 15.10; OR=1.68, 95% CI 1.45 to 1.88) and adults (OR=4.18, 95% CI 3.73 to 4.69; OR=1.66, 95% CI 1.49 to 1.85) than packs without. Among adolescents, 'Tropical Burst' named packs were more appealing (OR=1.43, 95% CI 1.20 to 1.72) than packs without a flavour name and among adults, 'Arctic Air' named packs were more appealing (OR=1.20, 95% CI 1.02 to 1.14). Adolescents and adults reported a preference for trying packs that displayed a flavour name, background colour or capsule image (b=0.104, b=0.702, b=1.316, p<0.001 and b=0.126, b=0.619, b=0.775, p<0.001). CONCLUSIONS: Colours and flavour capsule images appeal to adolescents and adults in Mexico. Mexico should consider adopting plain packaging to reduce appeal and interest.

Evaluating the impact of plain packaging among Canadian smokers: findings from the 2018 and 2020 ITC Smoking and Vaping Surveys.

BACKGROUND: In February 2020, Canada implemented plain packaging without any changes to the size and content of health warning labels (HWLs), which were last updated in 2012 (pictorial HWLs on 75% of the pack front and back). This pre-post evaluation study assessed the impact of plain packaging in Canada on: (1) pack appeal; (2) HWL effectiveness; and (3) support for plain packaging. Additionally, a quasi-experimental design was used to assess the Canadian results relative to two comparator countries: Australia, where plain packaging (with new larger HWLs) was implemented in 2012, and the United States (USA), where plain packaging has not been implemented and the same text warnings have appeared on cigarette packs since 1985. METHODS: Data are from adult smokers who participated in the 2018 and/or 2020 International Tobacco Control Smoking and Vaping Surveys in Canada (n=4600), Australia (n=1834) and the USA (n=3046). Online surveys were conducted before (February to July 2018) and after (February to June 2020) the implementation of plain packaging in Canada. Adjusted regression analyses were conducted on weighted data. RESULTS: Plain packaging was associated with a significant increase in the percentage of Canadian smokers who did not like the look of their cigarette pack (2018: 28.6% vs 2020: 44.7%, p<0.001), whereas no change in pack appeal was observed among smokers in Australia and the USA over the same period. Plain packaging was not associated with changes in HWL effectiveness in Canada. Support for plain packaging increased significantly among Canadian smokers (2018: 25.6% vs 2020: 33.7%, p<0.001). CONCLUSIONS: Plain packaging in Canada substantially reduced pack appeal and increased support for the policy among adult smokers; however, there was no increase in the effectiveness of Canada's 8-year-old HWLs. The impact of plain packaging on health warning effectiveness may depend on the design of the warnings and length of time since implementation.

Straw cigarette branding: misleading descriptors and a new Marlboro man.

BACKGROUND: Straw cigarettes are hand-rolled tobacco in a corn straw, common in Brazil and believed to be less harmful by consumers. Traditionally consumed in rural areas and by men, a recent increase in use among young people in urban areas was observed. This study assessed marketing appeals of straw cigarette packaging in Brazil. METHODS: Following a systematic protocol, unique straw cigarette packs were purchased in 2013, 2016 and 2019 from three cities: Manaus, Salvador and São Paulo. Packs were double-coded for the absence/presence of marketing appeals (ie, luxury/quality, masculinity, classic/timeless, flavours and less harm). RESULTS: The number of unique straw cigarette packs purchased as part of the overall sample increased in the most recent collection: 2.3% (n=3), 1.3% (n=2) and 15.5% (n=27) in 2013, 2016 and 2019, respectively. Across the years, all packs presented luxury/quality elements (eg, images of crests); 93.8% (n=30) included the word 'artisanal'. Masculine appeal (eg, images of men) was present on 56.3% (n=18) of packs. Almost half had classic/timeless elements, including the words 'tradition'/'original'. In 2019, 59.3% (n=16) of the packs were flavoured compared with none in previous years. Over a quarter of all packs presented a less harm appeal (eg, 'smooth'). CONCLUSION: We identified an increase in availability of unique straw cigarette packs, strong branding and use of misleading descriptors on the packs. The adoption of plain packaging and the implementation of Brazil's additive ban could help to reduce the appeal of straw cigarettes and curb the current increase in use among youth.

Influence of cigarette packet branding and colours on young male smokers' recognition, appeal and harm perceptions of tobacco brands in Cambodia: a mixed-methods study.

OBJECTIVES: To explore how cigarette packet branding and colours influence young male smokers' perceptions of tobacco brands in Cambodia. DESIGN: Mixed-methods study. SETTING: Worksites, living accommodations, a university and public locations in Phnom Penh, Cambodia. PARTICIPANTS: 147 male Cambodian smokers (18-24 years). INTERVENTIONS: Participants were shown mock-up pictures of different cigarette packet branding and colour variations and asked to respond to close-ended and short-response questions. OUTCOME MEASURES: Brand recognition, appeal and harm perceptions of cigarette packet branding and colours. RESULTS: When shown three packets with brand names removed, 98.6% of participants recognised packet one as Mevius brand, 21.1% recognised packet two as Marlboro and 38.8% recognised packet three as 555. For the three fully-branded and three matching plain packets, most participants selected a fully-branded packet as the most appealing taste (83.0%) and most appealing to youth (81.7%). Participants described their chosen brand as appealing due to beliefs about its superior taste/quality, reduced harm and symbolic attitudes surrounding tobacco brands and smokers of different brands in a social status hierarchy. When shown six different colours of unbranded packets, participants selected the blue packet (51.0%) as the most appealing for taste, the white packet as the least harmful (25.2%), and the red (15.0%) and black (12.9%) packets as the most harmful to health. They described their associations of packet colours with abstract imagery concerning smoking-related harms and their future well-being. CONCLUSIONS: Findings suggest that packet branding and colours influence young male smokers' recognition, appeal and harm perceptions of tobacco brands in Cambodia and remain an influential marketing tool for tobacco companies where advertising is banned. Consequently, Cambodia and other low and middle-income countries in Southeast Asia should implement plain packaging.

Perceived Influence of Plain Cigarette Packaging on Smoking Behavior: A Systematic Review.

CONTEXT: Worldwide, the number of cigarette smokers is increasing. All tobacco products come in packs. Packaging and branding are important elements of advertising and promotion. The plain packaging concept introduced by the World Health Organization, where marketing elements such as branding appeal are removed from the cigarette pack, is said to be effective for reducing smoking habits. The objective of this systematic review was to determine the influence of plain packaging on smoking behavior. METHOD: This systematic review was conducted using 2 databases (Scopus and Web of Science). We did not search for unpublished reports. The search was performed from September 2020 to December 2020 in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The inclusion criteria were original article that used a qualitative or quantitative method, English-language article, published in 2016-2020, and availability of full-text article. RESULTS: A total of 15 studies were included. All of the studies had adequate methodological quality. Most of the studies reported the effectiveness of plain packaging in preventing smoking initiation among nonsmokers. However, more studies reported no effect of plain packaging on smoking behavior among smokers. Furthermore, there was a greater impact of plain packaging on smoking behavior among female smokers and those who had recently started smoking. CONCLUSIONS: Plain packaging is more effective for evoking negative smoking behavior among nonsmokers than among smokers. As many of the included studies did not stratify the results based on age group and gender, future research should address these issues.

Cannabis edibles packaging: Communicative objects in a growing market.

BACKGROUND: Cannabis edibles were legalized for recreational use across Canada in October 2019. The Canadian Cannabis Act requires legally produced edibles to be sold in plain single-color packages with limited branded elements and prominent health warning labels, serving size and nutritional information, and product ingredients including amounts of cannabis compounds. Little research, however, assesses what consumers think of standardized packaging, and how product packaging influences perceptions of cannabis edibles. METHODS: Eight focus groups with young adults (ages 18-24; n = 57) were conducted in November 2018. Participants were recruited from a Canadian university, and asked to assess sample images of cannabis packaging approved by Health Canada. They then discussed the information they would like to see on packages. Focus group discussions were transcribed and analyzed using a descriptive, qualitative approach following methods of process evaluation and inductive coding. RESULTS: Discussions generally pertained to four main themes: dosage and consumption recommendations; food and nutritional information; concerns for children; and health warning labels. Participants suggested improvements for cannabis packaging, including standardized THC units, non-numerical consumption instructions, and unit-dose packaging. Instead of recommending packaging that deters consumption, participants requested packaging features that promote safe consumption by adults while also protecting children. Findings reveal how packages function as communicative objects that convey meanings about safety and risk, yet these meanings may not resonate with Canadian young adults' perceptions of cannabis as relatively safe. CONCLUSIONS: While the packaging regulated for use in Canada may be assumed, due to its plain, standardized format, to communicate "little", we highlight tensions in the meanings of such packaging to young adults-especially around competing ideas related to safety and risk.

Minimising carbon and financial costs of steam sterilisation and packaging of reusable surgical instruments.

BACKGROUND: The aim of this study was to estimate the carbon footprint and financial cost of decontaminating (steam sterilization) and packaging reusable surgical instruments, indicating how that burden might be reduced, enabling surgeons to drive action towards net-zero-carbon surgery. METHODS: Carbon footprints were estimated using activity data and prospective machine-loading audit data at a typical UK in-hospital sterilization unit, with instruments wrapped individually in flexible pouches, or prepared as sets housed in single-use tray wraps or reusable rigid containers. Modelling was used to determine the impact of alternative machine loading, opening instruments during the operation, streamlining sets, use of alternative energy sources for decontamination, and alternative waste streams. RESULTS: The carbon footprint of decontaminating and packaging instruments was lowest when instruments were part of sets (66-77 g CO2e per instrument), with a two- to three-fold increase when instruments were wrapped individually (189 g CO2e per instrument). Where 10 or fewer instruments were required for the operation, obtaining individually wrapped items was preferable to opening another set. The carbon footprint was determined significantly by machine loading and the number of instruments per machine slot. Carbon and financial costs increased with streamlining sets. High-temperature incineration of waste increased the carbon footprint of single-use packaging by 33-55 per cent, whereas recycling reduced this by 6-10 per cent. The absolute carbon footprint was dependent on the energy source used, but this did not alter the optimal processes to minimize that footprint. CONCLUSION: Carbon and financial savings can be made by preparing instruments as part of sets, integrating individually wrapped instruments into sets rather than streamlining them, efficient machine loading, and using low-carbon energy sources alongside recycling.

Analysis of wedding appeals on cigarette packs in China.

INTRODUCTION: Exchanging or gifting cigarettes is a common practice in Chinese culture, often occurring during weddings to connote celebrations and happiness. We examined Chinese cigarette packs for wedding terminology and imagery to assess the extent to which packs are marketed for such occasions. METHODS: Cigarette packs were collected from Beijing, Guangzhou, Shanghai, Kunming and Chengdu in February 2017 using a systematic protocol designed to capture unique packs. Packs were coded by two independent coders for text and imagery of traditional Chinese wedding symbols, such as double happiness, dragon and phoenix, and other culturally specific phrases and images associated with weddings in China. RESULTS: From the sample of 738 unique cigarette packs, 68 (9.2%) contained either lexical and/or imagery appeals for wedding gifting. Of these 68 packs, 65 contained both lexical and imagery appeals, 1 pack had only a lexical appeal and 2 packs only included an imagery appeal. The most common appeal was 'double happiness' found on 56 packs (82.4%) for both lexical and imagery, followed by 'dragon and phoenix' found lexically on 12 packs (17.6%), and through imagery on 15 packs (22.1%). CONCLUSIONS: Chinese tobacco manufacturers take full advantage of the cigarette gifting and sharing culture demonstrated by packs with imagery and terminology specific to weddings. With only a 35% text health warning label, manufacturers have much real estate to make packs attractive for gifting on such occasions. Implementing plain packaging policies may be effective in decreasing gifting attractiveness for cigarette packs.

The Short-term Impact of Standardised Packaging on Smoking and Snus Use in Norway.

INTRODUCTION: Standardised packaging on tobacco products was required in Norway July 1, 2018. We report pre-registered analyses of the potential impact on daily smoking and on daily snus use among women and men. METHODS: Interrupted time series (segmented regression) on repeated cross-sectional surveys (2012-2019) from two sources: probability samples (Registry Sample, N = 46,957) and market research samples (Market Research Sample, N = 64,465) of Norwegian adults aged 16-79. Self-reported daily smoking and snus use were regressed on a step change impact variable, controlled for trend and demographics (sex, age, region, and education based on national registers in the Registry Sample, and self-reported in the Market Research Sample). RESULTS: There were tendencies of a decline in smoking (Odds Ratio [OR] = 0.94; 95% confidence interval [CI] = 0.87, 1.02; lower-tail p-value [Plower] = 0.07), and women's snus use (OR = 0.89; CI = 0.77, 1.03; Plower = 0.06), but not men's snus use (OR = 1.01; CI = 0.92, 1.11; Plower = 0.59). Analyses using only the Registry Sample did not detect declines in smoking (OR = 0.99; CI = 0.88, 1.11; Plower = 0.43) or women's snus use (OR = 0.99; CI = 0.80, 1.24]; Plower = 0.48), and indicated no decline in men's snus use (OR = 1.18; CI = 1.03, 1.35; Plower = 0.99). Exploratory analyses suggested potential acceleration of the declining trend in smoking (change in trends, OR = 0.97) and of the increasing trend in men's snus use (OR = 1.03). CONCLUSIONS: The analyses indicate that standardised packaging in Norway did not produce a decline in men's snus use. Results are inconclusive regarding smoking and women's snus use. Exploratory analyses indicated a decrease in smoking and an increase in men's snus use. IMPLICATIONS: We could not confirm or disconfirm whether standardised packaging is an effective tobacco control measure in a Norwegian context. According to our analyses, standardized packaging may have effects on smoking prevalence and women's snus use, but is unlikely to reduce men's snus use. The present results may reflect higher effectiveness of standardised packaging for products with stronger health warnings. As the results varied according to samples and outcomes, the study underlines the importance of pre-registering future analyses on this topic. Future confirmatory research should test models of gradual impact of standardised packaging.

Implementation of MPOWER Package in the South-East Asia Region: Evidence from the WHO Report on the Global Tobacco Epidemic (2009-2021).

The WHO MPOWER package is a set of six evidence-based and cost-effective measures which was introduced on 7 February 2008 to facilitate the implementation of the provisions of the WHO Framework Convention on Tobacco Control at the ground level. These measures are: Monitoring tobacco use and prevention policies (M); Protecting people from tobacco smoke (P); Offering help to quit tobacco use (O); Warning about the dangers of tobacco (W); Enforcing bans on tobacco advertising, promotion and sponsorship (E); and Raising taxes on tobacco (R). Since its launch, the MPOWER package has become the guiding principle for all the countries of the South-East Asia Region in their crusade against the tobacco epidemic. This review article tracks the implementation of the MPOWER measures in the 11 member countries of the Region based on the last seven WHO Report on the Global Tobacco Epidemic (GTCR), i.e., GTCR2/2009-GTCR8/2021. This is with an aim to enable the countries to review their progress in implementing the MPOWER measures and to take steps to improve their advancement towards reducing the demand for tobacco products at the country level.

The packaging and clean method contribute to insulation failure of electrosurgical instruments.

ABSTRACT: With the rapid development of medical technology, the use of electrosurgical instruments is dramatically increased in various types of surgery. However, the damage of the insulation layer of the reusable electrosurgical instrument often causes surgical accidents. The procedures of packaging and cleaning contribute to many damages to insulating layer of reusable electrosurgical instruments.Various types of reusable electrosurgical instruments were detected for insulation failures, conduction failures, short-circuit by using a high-voltage detector, DIATEG (Morgate company). In addition, reusable electrosurgical instruments were detected for insulation failures after packaging and cleaning by different procedures.13.1% (129/740) electrosurgical instruments had an insulation test failure; 6.2% (9/146) monopolar wires were with conduction failure; and 7.7% (16/207) bipolar wires were with short-circuit. Different packaging and cleaning procedures contribute to various degrees of damages to insulating property of reusable electrosurgical instruments.Insulation failure was a wide problem of reusable electrosurgical instruments, while fixed packaging method and mild cleaning procedures result in fewer damages to insulating property of reusable electrosurgical instruments.

Quarantine supervision of Wood Packaging Materials (WPM) at Chinese ports of entry from 2003 to 2016.

Exotic pests have caused huge losses to agriculture, forestry, and human health. Analyzing information on all concerned pest species and their origin will help to improve the inspection procedures and will help to clarify the relative risks of imported cargo and formulate international trade policies. Records of intercepted pests from wood packaging materials (WPM) from 2003 to 2016 in the China Port Information Network (CPIN) database were analyzed. Results showed that the number of intercepted pests from WPM was lowest in the first quarter and highest in the fourth one. The total number of interceptions increased each year, with 53.33% of intercepted insects followed by nematodes (31.54%). The original continent of most intercepted pests was Asia (49.29%). Xylophagous insects were primarily intercepted from Southeast Asian countries, whereas nematodes were primarily intercepted from Korea, Australia, Mexico, and other countries. WPM interception records were mainly concentrated in China's coastal inspection stations (98.7%), with the largest number of interceptions documented in Shanghai, followed by the inspection stations of Jiangsu Province. The proportion of pest taxa intercepted by the Chinese provinces' stations each year is becoming increasingly balanced. The number of pest disposal treatment measures for intercepted cargoes with dead non-quarantine pests increased significantly from 2012 to 2016. This reflects the fact that Chinese customs inspection stations are becoming increasingly scientific and standardizing the interception and treatment of WPM pests. The issues reflected in the database, with a view to providing a reference for future work by customs officers and researchers.

Fabrication of Paper Sheets Coatings Based on Chitosan/Bacterial Nanocellulose/ZnO with Enhanced Antibacterial and Mechanical Properties.

Here, we designed paper sheets coated with chitosan, bacterial cellulose (nanofibers), and ZnO with boosted antibacterial and mechanical activity. We investigated the compositions, with ZnO exhibiting two different sizes/shapes: (1) rods and (2) irregular sphere-like particles. The proposed processing of bacterial cellulose resulted in the formation of nanofibers. Antimicrobial behavior was tested using E. coli ATCC® 25922™ following the ASTM E2149-13a standard. The mechanical properties of the paper sheets were measured by comparing tearing resistance, tensile strength, and bursting strength according to the ISO 5270 standard. The results showed an increased antibacterial response (assigned to the combination of chitosan and ZnO, independent of its shape and size) and boosted mechanical properties. Therefore, the proposed composition is an interesting multifunctional mixture for coatings in food packaging applications.

All-biobased transparent-wood: A new approach and its environmental-friendly packaging application.

Transparent-wood (TW) is an emerging research topic that can be applied to biobased products. However, it is necessary to fill pores in TW with natural substances to prepare all-biobased TW. This paper reports an all-biobased TW by infiltrating cellulose nanofiber (CNF) and chitosan (CTS) suspensions into the bleached wood. CNF was isolated by combining the chemical and physical methods, and CTS was dissolved in acetic acid, and they were infiltrated into the pores of the bleached Fir veneer wood using a vacuum jar. The CNF and chitosan effects on the mechanical properties of the TW were studied, and the morphologies, crystallinity index, water contact angle, antioxidant, thermal degradation, and UV-shielding properties were investigated. The prepared TW showed 80 % total transmittance and 30-60 % haze, suitable for solar cell application. The all-biobased TW showed good thermal stability up to 315 °C and excellent UV shielding property for UV-B and UV-C. The antioxidant property of the CTS-TW significantly increased as compared to the original wood. The CNF-TW showed considerable tensile strength and yield strength of more than 200 % improved from the original wood. The potential for environment-friendly packaging applications was demonstrated by making a bag, medicine packaging, and straw for a drink.
