Study of non-volatile components of biodegradable polyester and polylactic acid blend identifies 37 different compounds including plasticizers and oligomers, some seen only in migration experiments
Low migration of lead and arsenic measured in food contact paper bought in Korea; resulting human exposure estimated to be within safe levels
Scientists detect high levels of bisphenol A in recycled polyethylene terephthalate, suggest monitoring BPA in rPET necessary to support ‘BPA-free’ claims
Review presents new analytical approaches to identify non-intentionally added substances in food packaging materials
Scientists review evidence on paraben preservatives acting as estrogenic endocrine disruptors; certain effects observed in animals not confirmed in humans; studies on parabens’ effects on immune and nervous system lacking
Study of bio-based food contact articles made of sugarcane bagasse or cellulose wood pulp labelled “natural”, “compostable”, or “biodegradable” finds PFAS and organophosphate esters (OPEs), a type of flame retardant and plasticizer; concentrations highest in baking papers; though purchased in Italy, some OPEs above EU regulatory concentration limit of 0.01 mg/kg
Scientists review chemical analytical approaches for food contaminants originating from packaging, including active packaging and novel biopolymers; call for thorough characterization of substances migrating from active packaging, including impurities, auxiliary compounds, potential biotransformation products
Several recent reviews examine the value chain of biobased polymers; discuss clarification of terms such as biobased, degradable, biodegradable, and compostable; define “biotechnological recycling (bio-recycling)” as the use of enzymes and microorganisms in a technological setting to biodegrade polymers; three biodegradable polymers assessed in marine field trials
ILSI North America holds first public food packaging conference; several FDA speakers shared updates from ongoing work in pre- and post-market FCM risk assessment
Scientists analyze volatile compounds migrating from single-use dishes made of wheat pulp or wood; products considered safe for food contact use with respect to volatiles’ migration; migration of non-volatile substances and safety of high-temperature applications requires further study
