Manufacturers are required to register products and mixtures containing nanomaterials; food contact materials are exempted
China revises regulation on new chemical substances
Government publishes final regulatory text, substance approval linked to persistent, bioaccumulative, and toxic properties; identity of new substances to be made publicly available after maximum period of 5 years; comes into force on January 1, 2021
Oligomers in biodegradable food packaging
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
Lead and arsenic in food contact paper
Low migration of lead and arsenic measured in food contact paper bought in Korea; resulting human exposure estimated to be within safe levels
BPA in recycled PET
Scientists detect high levels of bisphenol A in recycled polyethylene terephthalate, suggest monitoring BPA in rPET necessary to support ‘BPA-free’ claims
NIAS detection in food packaging materials
Review presents new analytical approaches to identify non-intentionally added substances in food packaging materials
Endocrine effects of parabens
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
Flame retardants above regulatory limits in some ‘eco-friendly’ baking papers
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
Chemical analytics of novel food packaging
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
Reviews examine biobased polymers
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
