“…An off‐odor with a smell of cat urine is reported to have occurred in cooked ham products packed in polyamide/ionomer laminate films (Piringer and Ruter 2000). A gas chromatograph (GC) study of such products was able to identify the presence of diacetone alcohol (DAA), which was used in the printing ink of the film that subsequently migrated into the laminate.…”

Food packaging, although an integral part of the food chain, has a major drawback in that, often, the packaging material interacts with the flavor constituents of the food, causing either a selective or an extensive loss of desirable food flavors or absorption of undesirable off-flavors from the packaging material, thereby resulting in an eventual loss of quality of the packaged food item. The process is called "scalping" and is of great concern to the food industry, which is always looking out for new avenues in "packaging solutions" for its final product quality needs. The review highlights the various attributes of the scalping process, explores approaches to the reduction of the manifested undesirable effects, and covers other relevant aspects.

“…Piringer and Baner collated diffusion data for HDPE, LDPE, and polypropylene (PP) from many literature reports 12 . However, they provided only limited information about some of the polymers, solutes, and methods, so we included or excluded these data on a case‐by‐case basis.…”

“…Consequently, recent work has been aimed at providing clinically relevant exposure estimates using physics‐based mass transport models 7,8 . Such approaches have been used in the regulatory context of food packaging for over two decades 9–13 . Until recently, physics‐based modeling of leaching from medical devices had not been widely considered as an approach to predict patient exposure to leachables, owing to the difficulties of modeling transport in the peri‐implant environment (i.e., diffusivity, solubility, and advection in various tissues) 14,15 .…”

The approach was drawn from a different regulatory field, where the focus was on the leaching of additives from food packaging polymers into consumer foodstuffs 11–13 . Using this approach, a set of 19 polymers were grouped into 4 categories based on their physical properties (e.g., density, glass transition temperature T g ) and a modestly sized diffusion dataset that was focused on color additives 16 .…”

Robust estimates of solute diffusivity in polymers for predicting patient exposure to medical device leachables

Medical devices often include polymeric components, which contain additives or contaminants that may leach into patients and pose a health risk. Previously, we proposed a mass transport model that conservatively estimates the leaching kinetics and only requires the solute's diffusion coefficient in the polymer, , to be specified. Because determining experimentally is time‐consuming, we also parameterized empirical models to estimate worst‐case values using only the solute molecular weight, . These models were based on a modest database and were limited to 19 polymers and larger solutes ( g/mol). Here, we assemble a much larger database, which enables us to construct more accurate models using a robust statistical approach, expanding the coverage to 50 device‐relevant polymers and smaller solutes ( g/mol). Then, we demonstrate several applications of these bounds, including modeling the release kinetics. Finally, we observe an interesting phenomenon, a discontinuous drop in of up to 25,000× for solutes with g/mol in glassy polymers. Using molecular simulations and cheminformatics tools, we propose a novel definition of the effective diameter of free volume channels in polymers, and we show that solutes larger than this channel size diffuse much more slowly.

European governments are addressing plastic pollution by implementing the Directive EU 2019/904 that bans single‐use items like cutlery, plates, straws, and beverage stirrers. One strategy proposed by several industries to continue their production is the conversion of single‐use items into multiuse items. Herein, the focus is on the production of polystyrene reusable plates and the suitability of this product for microwave and dishwasher use is assessed: in proper conditions, the structure is preserved without cuts or visible deformations, and the chemical stability is guaranteed. To get a full picture of the benefits and impacts of this new product, a life cycle assessment methodology is applied to compare the performances of one reusable plate with 20 single‐use plates. Results indicate that proper use is crucial: a reusable plate disposed after one use is more impactful than a single‐use plate. In contrast, the reuse of plates for 20 times allows to reduce carbon footprint and acidification potential. Eutrophication and ozone layer depletion, on the other hand, increase due to the washing phase. The solutions that can mitigate these issues and enhance the sustainability of the reusable plates include the improvement of the detergent compositions and the use of electricity from renewable sources.
