“…However, the study only considered standard polyethylene terephthalate (PET) and polycarbonate containers, which are not used in retort systems and do not need to withstand the rigors of this manufacturing process. More recently, a study on reusable plastic sports bottles found that the dishwashing process itself increased migration of plastic-related compounds into drinking water [81]. In products for vulnerable populations, these processes would be contraindicated.…”

Specialized products can be needed to help meet the nutrition requirements of vulnerable populations, including infants and young children, those who are ill, and older adults. Laws and regulations delineate distinct categories for such products including medical foods or formulated liquid diets, foods for special dietary use (FSDUs), infant formulas, and natural health products (NHPs). Yet, the literature is limited regarding the role and importance of functional and sustainable packaging for specialized products. This perspective review describes these unique product categories and the role of packaging as well as regulatory considerations. Furthermore, reviewed are how waste reduction strategies and emerging legislative/regulatory policies in the United States and Canada may not adequately address the functional packaging requirements for specialized products. The paper concludes by offering perspectives for emerging innovations and policy development for sustainability.

“…51 Tisler and co-workers found that alkyl PEG ethers migrated from reusable polyethylene (PE) water bottles. 52 The RT of alkyl PEG ethers is dependent on the number of ethoxylate (EO) groups in the molecule. Each EO group in the molecular chain increases the polarity of the molecule; therefore, the more EO groups present in an alkyl PEG ether, the earlier the chromatographic elution of the compound in reverse phase LC.…”

The identification of migrates from food contact materials (FCMs) is challenging due to the complex matrices and limited availability of commercial standards. The use of machine-learning-based prediction tools can help in the identification of such compounds. This study presents a workflow to identify nonvolatile migrates from FCMs based on liquid chromatography−ion mobility−high-resolution mass spectrometry together with in silico retention time (RT) and collision cross section (CCS) prediction tools. The applicability of this workflow was evaluated by screening the chemicals that migrated from polyamide (PA) spatulas. The number of candidate compounds was reduced by approximately 75% and 29% on applying RT and CCS prediction filters, respectively. A total of 95 compounds were identified in the PA spatulas of which 54 compounds were confirmed using reference standards. The development of a database containing predicted RT and CCS values of compounds related to FCMs can aid in the identification of chemicals in FCMs.

“…For example, durable plastics and their additives may need to withstand multiple (dish)washing cycles without (or with only minimal) leaching and/or transformation of embedded additives, or absorption of additional chemicals ( Section 6.1 ). 53 Additive migration during the intended use phase can accelerate the failure of plastic products and impede intended long-term use, e.g., due to product embrittlement or lack of the function initially provided by the additive ( Section S6.2 ). 54 Some additives may specifically contribute to increasing plastic longevity (e.g., photostabilizers), but sometimes, the protective function generates unintended negative impacts.…”

Integrating a Chemicals Perspective into the Global Plastic Treaty

Driven by the growing concern about plastic pollution, countries have agreed to establish a global plastic treaty addressing the full life cycle of plastics. However, while plastics are complex materials consisting of mixtures of chemicals such as additives, processing aids, and nonintentionally added substances, it is at risk that the chemical aspects of plastics may be overlooked in the forthcoming treaty. This is highly concerning because a large variety of over 10,000 chemical substances may have been used in plastic production, and many of them are known to be hazardous to human health and the environment. In this Global Perspective, we further highlight an additional, generally overlooked, but critical aspect that many chemicals in plastics hamper the technological solutions envisioned to solve some of the major plastic issues: mechanical recycling, waste-to-energy, chemical recycling, biobased plastics, biodegradable plastics, and durable plastics. Building on existing success stories, we outline three concrete recommendations on how the chemical aspects can be integrated into the global plastic treaty to ensure its effectiveness: (1) reducing the complexity of chemicals in plastics, (2) ensuring the transparency of chemicals in plastics, and (3) aligning the right incentives for a systematic transition.
