Tackling the toxics in plastics packaging.

The widespread use of plastic packaging for storing, transporting, and conveniently preparing or serving foodstuffs is significantly contributing to the global plastic pollution crisis. This has led to many efforts directed toward amending plastic packaging's end of life, such as recycling, or alternative material approaches, like increasingly using paper for food packaging. But these approaches often neglect the critical issue of chemical migration: When contacting foodstuffs, chemicals that are present in packaging transfer into food and thus unwittingly become part of the human diet. Hazardous chemicals, such as endocrine disrupters, carcinogens, or substances that bioaccumulate, are collectively referred to as "chemicals of concern." They can transfer from plastic packaging into food, together with other unknown or toxicologically uncharacterized chemicals. This chemical transfer is scientifically undisputed and makes plastic packaging a known, and avoidable, source of human exposure to synthetic, hazardous, and untested chemicals. Here, I discuss this issue and highlight aspects in need of improvement, namely the way that chemicals present in food packaging are assessed for toxicity. Further, I provide an outlook on how chemical contamination from food packaging could be addressed in the future. Robust innovations must attempt systemic change and tackle the issue of plastic pollution and chemical migration in a way that integrates all existing knowledge.

The impact of front-of-package claims, fruit images, and health warnings on consumers' perceptions of sugar-sweetened fruit drinks: Three randomized experiments.

We aimed to examine the impact of claims, fruit images, and health warnings on consumers' perceptions of fruit-flavored drinks with added sugar (i.e., "fruit drinks"). We conducted three 2x2x2 randomized experiments with online convenience samples of U.S. adults (Study 1 n = 2139 in 2018, current e-cigarette users and smokers; Study 2 n = 670 in 2018, current e-cigarette users; Study 3 n = 1006 in 2019, general sample). Participants viewed a fruit drink that differed in the presence of a "100% Vitamin C" claim, a fruit image, or a health warning. On average across the three studies, consumers who saw a claim on a fruit drink believed that the drink was more healthful than those who did not see the claim (mean average differential effect (ADE) = 0.66, p < .001); they were also more interested in consuming the drink (mean ADE = 0.38, p = .001). The health warning decreased perceived product healthfulness (mean ADE = -0.65, p < .001) and consumption interest (mean ADE = -0.49, p < .001). The fruit image had no effect on perceived product healthfulness (mean ADE = 0.03, p = .81) or purchase intentions (mean ADE = -0.04, p = .77). In Study 1 and Study 2, there were no interactions between claims, images, or warnings (all p > .05). In Study 3, the "100% Vitamin C" nutrition claim only increased perceived product healthfulness when the drink did not also have a health warning (interaction p < .05). These findings suggest that 100% Vitamin C claims increase the appeal of fruit drinks, whereas health warnings decrease the appeal. Together, these studies support policies to restrict marketing and require health warnings on sugar-sweetened beverage packaging.

Trends in and Correlates of Use of Roll-Your-Own Cigarettes: A Population Study in England 2008-2017.

INTRODUCTION: Understanding the use of cheaper roll-your-own (RYO) cigarettes may have implications for tobacco tax policy. We examined trends in RYO cigarette use in England between 2008 and 2017, and characterized users' sociodemographic and smoking profiles. METHODS: We used data from 211 469 respondents to a survey representative of the adult (≥16 years) population. In current smokers across the entire study period (n = 43 389), we assessed multivariable associations between cigarette type (RYO or factory-made [FM]) and sociodemographic and smoking characteristics. Among current smokers in 2008 and 2017 (n = 7685), we tested interactions between year and cigarette type to assess the stability of each characteristic. RESULTS: Between 2008 and 2017, FM cigarette use declined from 15.3% to 9.2% whereas RYO use increased from 6.7% to 8.1%. Greater odds of RYO use were observed among younger, male smokers from lower social grades, who were more addicted and used electronic cigarettes (ORrange = 1.28-1.86, p < .001). Lower odds of RYO use were observed among nondaily smokers, those with high motivation to stop, and higher spending on smoking (ORrange = 0.46-0.89, p ≤ .001). The RYO smoker profile was relatively stable between 2008 and 2017. However, compared with FM use, RYO use increased in younger (p < .001) and female (p = .019) smokers, and there was a relatively smaller decline in the proportion cutting down or trying to quit (p = .004). CONCLUSION: In England, RYO use increased when overall smoking prevalence and FM use decreased. The profile of RYO smokers remained relatively stable, with users typically younger, male, more addicted, deprived, spending less on smoking, and less inclined to quit than FM smokers. IMPLICATIONS: This population-based study provides novel insight into recent trends in RYO use in England, providing an up-to-date understanding of the profile of RYO smokers. Without the consistent application of tax across the range of combustible products, smokers who are more dependent are able to capitalize on the lower cost of RYO in order to continue smoking, undermining the potential benefit of taxation on cessation.

Introduction of Standardized Tobacco Packaging During a 12-Month Transition Period: Findings From Small Retailers in the United Kingdom.

INTRODUCTION: Factory-made cigarettes (FMC) and roll-your-own (RYO) tobacco have had to be produced in standardized packaging since May 20, 2016 in the United Kingdom, with a minimum pack size of 20 sticks for FMC and 30 g for RYO. Manufacturers and retailers were given a 12-month transition period. METHODS: An observational study was conducted using monthly Electronic Point of Sale data from 500 small retailers in England, Scotland, and Wales, between May 2016 and May 2017. The 20 top selling tobacco products (15 FMC, 5 RYO) were monitored to observe when standardized packs were first introduced, the proportion of retailers selling each fully branded and standardized product, and the average number of monitored fully branded and standardized products sold by each retailer. The number of unique tobacco-related product codes sold by each retailer was also recorded each month. RESULTS: Eighteen of the fully branded products continued to be sold throughout the transition period and no standardized variants were sold in the first 5 months. It was not until month eleven that the average number of standardized products sold by retailers exceeded the fully branded products. The average number of unique tobacco-related product codes sold by each retailer decreased by a third over the transition period. CONCLUSIONS: Tobacco companies used the transition period to delay the removal of fully branded products and gradually introduce standardized variants. This staggered introduction may have mitigated some of the immediate intended effects of the legislation by desensitizing consumers to new pack designs. IMPLICATIONS: Evaluation research from countries which have introduced standardized packaging for tobacco products is key to help inform future implementation. This is the first study to monitor the transition from fully branded to standardized products using real-time retail data. The findings demonstrate that tobacco companies delayed the introduction of standardized products and removal of fully branded packaging. Countries seeking to introduce standardized packaging should consider what length of transition is allowed, as the protracted 12-month period in the United Kingdom appeared longer than needed to transition stockholding and may have mitigated immediate intended effects by desensitizing consumers to new pack designs.

The Response of Retailers in Scotland to the Standardised Packaging of Tobacco Products Regulations and Tobacco Products Directive.

INTRODUCTION: With most marketing channels prohibited, the retail environment has assumed greater importance for tobacco companies, even in markets with a ban on the open display of tobacco products. Research has yet to qualitatively explore how retailers respond to standardized packaging in a country where this has been introduced. METHODS: As part of the DISPLAY study, face-to-face interviews were conducted with 24 small retailers in Scotland between May 23 and June 26, 2017; the interviews were conducted after The Standardised Packaging of Tobacco Products Regulations and the Tobacco Products Directive were fully implemented. RESULTS: We found high retailer compliance with the legislation. With price-marked packs and packs containing less than 20 cigarettes and 30 g of rolling tobacco banned, retailers stated that this helped simplify ordering and stock management. The removal of price-marked packs also allowed them some flexibility to set their own prices, but many chose to stick closely to recommended retail price in order to remain competitive and avoid complaints from customers. In contrast to one of the tobacco industry's arguments against standardized packaging, most retailers suggested that transaction times had not increased, even though the changes had only recently come into force. CONCLUSIONS: This study challenges some of the arguments used against standardized packaging and provides an insight into the storage and pricing strategies adopted by retailers following the removal of price-marked packs. IMPLICATIONS: This study explores the response of the retailers to the introduction of standardized tobacco packaging and provides an insight into the storage and pricing strategies adopted by retailers following the removal of price-marked packs. It explores the importance of the retailer in tobacco companies' desire to maintain tobacco sales and challenges some of the arguments used against standardized packaging, such as an increase in transaction times. Countries seeking to introduce standardized packaging should monitor the experiences of retailers, preferably from preimplementation through to post implementation, to help understand how retailers respond to this policy and to inform compliance.

Waterpipe tobacco package warning exposure's impact on risk perceptions and use among young adults in the USA: a longitudinal analysis of the population assessment of tobacco and health study.

BACKGROUND: Although Food and Drug Administration (FDA)-mandated waterpipe tobacco warnings were not required until August 2018, some waterpipe tobacco packaging (WTP) sold in the USA, contained warnings prior to this date. We examined the prevalence of WTP warning exposure and whether exposure influenced risk perceptions or use among young adult (aged 18-24 years) current waterpipe users. METHODS: We used data from waves 1 (2013-2014) and 2 (2014-2015) of the Population Assessment of Tobacco and Health Study, a nationally representative longitudinal study of US adults and youth. We conducted logistic regression analyses to identify factors associated with wave 1 warning exposure, and whether wave 1 WTP warning exposure predicted wave 2 relative risk perceptions and waterpipe use. RESULTS: More than one-third of our sample (35.9%, 95% CI 33.5 to 38.4) reported past-month WTP warning exposure. Exposure was higher among males (adjusted OR (AOR)=1.34, 95% CI 1.04 to 1.72), those who usually do not share the waterpipe (AOR=3.10, 95% CI 1.45 to 6.60), those who purchased waterpipe tobacco (AOR=1.73, 95% CI 1.28 to 2.34), and those with a regular brand (AOR=1.84, 95% CI 1.26 to 2.68). Those exposed to WTP warnings at wave 1 were more likely than those not exposed to perceive waterpipe tobacco to be as or more harmful than cigarettes at wave 2 (AOR=1.35, 95% CI 1.02 to 1.78). There was no association between wave 1 WTP exposure and wave 2 waterpipe use. CONCLUSIONS: More than one-third of US young adult current waterpipe users reported WTP warning exposure prior to FDA-mandated warning implementation. Findings suggest the mandated warning may result in high exposure among users; it will be critical to assess exposure's impact on risk perceptions and behaviour after FDA-mandated warnings are implemented.

Marketing with tobacco pack onserts: a qualitative analysis of tobacco industry documents.

BACKGROUND: Cigarette packs are a form of advertising that distributes brand information wherever smokers go. In the 21st century, tobacco companies began using onserts on cigarette packs to communicate new advertising messages to smokers. METHODS: We reviewed tobacco industry documents dated 1926 to 2017 to identify how the tobacco industry developed and used onserts in marketing and to serve the industry's political and legal objectives. RESULTS: Onserts added to cigarette packs became a more cost-effective way for brands to market in the year 2000. Manufacturers then began studying them, finding that new messages were appealing, while repeated messages were ignored. By 2005, tobacco companies were using onserts to effectively communicate about new tobacco products and packaging changes. They also used repeated 'corporate responsibility' messages that were, according to the industry's own research, likely to be ignored. CONCLUSIONS: Tobacco companies have expanded on cigarette pack-based advertising. Twenty-first century onserts simultaneously seek to increase sales using materials that are novel, attractive and provide independent value, while undercutting public health messages about the risks of tobacco use using materials that repeat over time and are comparatively unattractive. Health authorities can use this industry research to mandate onserts to communicate effective health messages.

Over-Time Impacts of Pictorial Health Warning Labels and their Differences across Smoker Subgroups: Results from Adult Smokers in Canada and Australia.

Introduction: This study examines patterns of change in different smoker subgroups' responses to new pictorial health warning labels (HWLs) over the initial, two year post-implementation period in Canada, where HWLs include package inserts with cessation messages, and Australia, where "plain" packaging (i.e., prohibition of brand imagery) was also implemented. Methods: Data were collected from online consumer panels in Canada (nsmokers = 3153; nobservations = 5826) and Australia (nsmokers = 2699; nobservations = 5818) from September 2012 to September 2014, with approximately 1000 adult smokers surveyed in each country every four months, using replenishment to maintain sample size. Data were analyzed using generalized estimating equation models where main effects and interactions among time, country, and socio-demographic factors on HWL responses (i.e., attention to HWLs; cognitive and behavioral responses to HWLs) were examined. Results: Over time, attention to HWLs declined but cognitive and forgoing responses to HWLs increased, in both Canada and Australia. In both countries, compared to smokers with low income and/or education, smokers with high income and/or education showed an increase over time in attention and cognitive responses to HWLs (p < .05). In Australia only, compared to older smokers, younger smokers showed less decline over time in attention and greater increase in cognitive and forgoing responses to HWLs (p < .001). Conclusions: Novel HWL policies in Canada and Australia appear effective in staving off "wear out" over the first 2 years after implementation, particularly amongst smokers who are from higher SES groups and, in Australia, who are younger. Implications: Previous research shows that the effects of health warning label (HWL) on smokers decline over time, but no studies to date have evaluated whether trends differ across socio-demographic groups. This study suggests that innovative policy configurations that combine prominent pictorial HWLs with inserts (Canada) and with "plain" packaging (Australia) may delay wear out over the first 2 years after implementation. While this study found evidence for wear out in attention to HWLs, other HWL responses (cognitive responses, forgoing cigarettes) actually increased over time, with greater increases amongst smokers with higher income and/or education.

How tobacco companies in the United Kingdom prepared for, and responded to, standardised packaging of cigarettes and rolling tobacco.

INTRODUCTION: As a result of the Standardised Packaging of Tobacco Products Regulations and Tobacco Products Directive, all packs of cigarettes (factory-made and hand-rolled) in the UK must be drab brown, display pictorial warnings on the principal display areas and contain no less than 20 cigarettes or 30 g of tobacco. The legislation was phased in between May 2016 and May 2017. Our objective was to monitor pack, brand and product changes preimplementation and postimplementation. METHODS: Our surveillance of the cigarette market involved a review of the trade press, a monthly monitor of online supermarkets and regular visits to stores, from May 2015 to June 2017. RESULTS: Before standardised packaging there were changes to the pack graphics (eg, redesigned packs and limited editions) and pack structure (eg, resealable inner foil) and the issue of a number of reusable tins. After standardised packaging, changes included newer cigarette pack sizes for some brand variants (eg, 23 and 24 packs). Changes to the branding prestandardised packaging included brand extensions, and poststandardised packaging included brand and/or variant name change, often with the inclusion of colour descriptors and brand migrations. Product changes prestandardised packaging included the introduction of novel filters (eg, filters with two flavour-changing capsules, tube filters, firmer filters and filters with granular additives). There was non-compliance with the legislation, with slim packs, which are not permitted, on sale after standardised packaging was implemented. CONCLUSIONS: Our findings highlight the need to monitor developments in markets introducing standardised packaging and have policy implications for countries considering this measure.

Tobacco product developments in the Australian market in the 4 years following plain packaging.

This paper aimed to identify continued and emerging trends in the Australian tobacco market following plain packaging implementation, over a period of substantial increases in tobacco taxes. Since 2012, our surveillance activities (including review of trade product and price lists, ingredient reports submitted by tobacco companies to government and monitoring of the retail environment) found several trends in the factory-made cigarette market. These include the continued release of extra-long and slim cigarettes and packs with bonus cigarettes, particularly in the mainstream and premium market segments; new menthol capsule products; other novel flavourings in cigarettes; filter innovations including recessed and firm filters; continued use of evocative and descriptive product names; the proliferation of the new super-value market segment; and umbrella branding, where new products are introduced within established brand families. Several similar trends were also observed within the smoking tobacco market. While not all of these trends were new to the Australian market at the time of plain packaging implementation, their continued and increased use is notable. Plain packaging legislation could be strengthened to standardise cigarette and pack size, restrict brand and variant names, and ban features such as menthol capsules and filters innovations that provide novelty value or that may provide false reassurance to smokers.

Graphic Health Warnings on Cigarette Packs: How Long Before the Effects on Adolescents Wear Out?

INTRODUCTION: To examine the long-term impact of graphic health-warning labels (GHWL) on adolescents' cognitive processing of warning labels and cigarette pack perceptions. METHODS: Cross-sectional school-based surveys of students aged 13-17 years residing in urban centers, conducted prior to GHWL introduction (2005) and 6 months (2006), 2 years (2008), and 5 years (2011) post-GHWL introduction. Students who had seen a cigarette pack in the previous 6 months or in 2006, who had seen GHWL were included in analyses (2005 n = 2,560; 2006 n = 1,306; 2008 n = 2,303; 2011 n = 2,716). Smoking stage, reported exposure to cigarette packs, cognitive processing of GHWL, and positive and negative perceptions of pack image were assessed. RESULTS: While cognitive processing of GHWL in 2006 and 2008 was greater than 2005 (p < .01), by 2011 scores had returned to 2005 levels. This pattern of change was consistent across smoking status groups. Pack image perceptions became more negative over time among all students, irrespective of smoking experience. While positive pack image ratings were lower in all subsequent years than 2005, the 2008 rating was higher than 2006 (p < .01). A significant interaction between survey time and smoking status (p < .01) showed that significant increases in positive pack ratings after 2006 only occurred among current and experimental smokers. CONCLUSIONS: When novel, GHWL on cigarette packs increase cognitive processing among adolescents. However, this effect diminishes after 5 years, suggesting more regular message refreshment is needed. Australia's adoption of plain packaging is intended to undermine positive pack appeal and increase warning salience.

Perceptions of U.S. and Canadian Cannabis Package Warnings Among U.S. Adults.

BACKGROUND: Cannabis warning labels can communicate risks, but there is little research on warning perceptions and differences by product type. METHODS: In a 2019 online survey, 1,000 U.S. adults (500 cannabis users and 500 cannabis non-users who used tobacco) were randomly assigned to view no warning or one of four U.S. or Canadian warnings displayed on images of packaging for dried flower or edible cannabis. The warnings described cannabis risks related to psychosis, addiction, lack of FDA oversight, and impaired driving. We used linear regression to examine perceptions of warnings and product harm as a function of product type (dried or edible) and warning. We examined which warning participants selected as most effective for discouraging youth use and impaired driving. RESULTS: Participants found the addiction warning (cannabis users: B = -1.04, p < 0.001; cannabis non-users: B = 1.17, p < 0.001) and psychosis warning (users: B = -0.65, p < 0.05; non-users: B = -0.71, p < 0.05) less believable than the driving warning but indicated that they learned more from the psychosis warning than the driving warning (users: B = 0.88, p < 0.01; non-users (B = 1.60, p < 0.001). Participants viewing any warning considered smoking cannabis to be more harmful than those viewing no warning (all p < 0.05). The psychosis warning was most frequently selected as the best warning for discouraging youth use. CONCLUSIONS: Warnings have the potential to educate consumers and impact cannabis harm perceptions. Warnings have similar effects across product types, potentially eliminating the need for product type-specific warnings. The association of cannabis use with risk for psychosis, a topic addressed in Canadian warnings, could be a useful topic of focus in U.S. warnings.

How effective is the plain packaging of tobacco policy on rates of intention to quit smoking and changing attitudes to smoking?

BACKGROUND: The aim of this study is to critically appraise the evidence for the effectiveness of the plain packaging of tobacco products policy. METHODS: A systematic approach to a literature review was undertaken using five databases: PubMed, MEDLINE, Google Scholar, Global Health and Legacy Tobacco Documents Library. Quantitative and qualitative studies that evaluate attitudes towards smoking, starting smoking and quitting intentions when plain packaging use is compared with standard cigarette packaging use were included. RESULTS: A total of 1923 studies were identified. After inclusion and exclusion criteria were applied, nine studies were included in the review. The overall quality of the data was variable but a significant number of the studies had major methodological flaws. However, data analysed in the literature review suggest that exposure to plain packaging increases intention to quit amongst exposed individuals, increases negative attitudes to both smoking and starting smoking. CONCLUSION: Although the evidence for plain packaging of tobacco is not strong, the evidence that is available indicates that it is an effective tobacco cessation policy.

One size does not fit all: how the tobacco industry has altered cigarette design to target consumer groups with specific psychological and psychosocial needs.

AIMS: To identify whether the tobacco industry has targeted cigarette product design towards individuals with varying psychological/psychosocial needs. DESIGN: Internal industry documents were identified through searches of an online archival document research tool database using relevancy criteria of consumer segmentation and needs assessment. FINDINGS: The industry segmented consumer markets based on psychological needs (stress relief, behavioral arousal, performance enhancement, obesity reduction) and psychosocial needs (social acceptance, personal image). Associations between these segments and smoking behaviors, brand and design preferences were used to create cigarette brands targeting individuals with these needs. CONCLUSIONS: Cigarette brands created to address the psychological/psychosocial needs of smokers may increase the likelihood of smoking initiation and addiction. Awareness of targeted product development will improve smoking cessation and prevention efforts.

Advances in medical packaging.

The specialist medical packaging sector is in a period of change. Product innovations, new manufacturing methods, and increasingly stringent demands are the features of today. Aside from the evolving requirements of medical device manufacturers, the driving forces for change are prompted by new packaging legislation, environmental pressures, and, above all, the need to maximize cost effectiveness. The adoption of new production processes and products looks set to increase.

Latest medical applications of polypropylene.

PP volumes for use in medical applications increase every year for some obvious reasons. The polymer can be processed by practically all techniques and sterilisation and transparency processes, and its properties are continuously improved. Furthermore, it can replace many other materials, and is attractive from a cost and versatility perspective.

The move to combine CEN and ISO medical packaging standards.

Long-held plans for a universally accepted international standard are showing signs of progress and hopes are high that this could become a reality by 2004.
