8th annual Food Packaging Forum workshop focuses on linking policy-making with scientific research to improve the safety of food contact materials; video recordings, presentation slides, and summary articles now available online
Microplastic effects on colon cells, blood lymphocytes, and gut-liver axis
Two in vitro studies analyze plastic particle effects using human cells; find polystyrene (PS) particles change metabolism of human colon cells similar to a carcinogen; PS nanoplastics may have cytotoxic and genotoxic potential on human blood lymphocytes; mouse study indicates microplastics increase risk of insulin resistance; researchers calculate particle ingestion from takeaway containers
Searching for safer plasticizers
Scientists evaluate a panel of novel plasticizers for in vitro effects on testicular function; propose alternatives to phthalates
Studies investigate circular economy barriers, consumer perceptions
Recent set of articles in peer-reviewed scientific journals review current barriers in flexible plastics to achieving circular economy, recommends regulatory policies be tailored to individual steps in supply chain; consumers easily confused by plastic waste management system, recycling processes, biodegradability claims; researchers instead propose food system shift towards decentralization, shorter supply chains
Nanoplastics affect gene expression in the placenta and reproductive health, scientists find
Study using perfused human placental tissue demonstrates polystyrene nanoplastics affect expression of inflammation and iron homeostasis-related genes; review summarizes that small plastic particles can enter reproductive organs and affect reproductive health, however further research needed to verify the results and assess mechanisms of reproductive toxicity
Studies discuss EDC sources, exposure, and human health effects
Scientific studies investigate human endocrine-disrupting chemical (EDC) exposures and effects; Canadian study finds bisphenols migrate from baby bottles and sippy cups; reviews report of widespread presence of bisphenols, parabens, and benzophenones in human breast milk and addresses current misunderstandings about the impacts of EDCs on child health
FCCmigex dashboard now has in-depth plastics page
Food Packaging Forum publishes interactive tool dedicated to exploring plastic food contact chemical research; released as an update of the Database on Migrating and Extractable Food Contact Chemicals (FCCmigex) dashboard; users can filter data by 12 polymer types, includes 1975 chemicals detected in plastics
FCCmigex dashboard updated with more features
The Food Packaging Forum updates Database on Migrating and Extractable Food Contact Chemicals (FCCmigex) dashboard; free and interactive tool now includes filter for additional food contact materials like adhesives, coatings, and printing inks; full synchronization between data and reference pages
Oligomer migration from PET and Tritan™
Scientists find cyclic polyethylene terephthalate (PET) oligomers migrate into fatty food simulants but not olive oil; levels higher from recycled compared to virgin PET; comprehensive extraction and migration experiments of Tritan™ products find oligomer migration from bottles of no toxicological concern but microwaveable containers were non-suitable for food heating
Bisphenols in thermal paper extracts and drinking bottle migrates
Scientific studies analyze bisphenol content in thermal papers and migrates from reusable drinking bottles; of 14 analyzed bisphenols 4 detected in thermal receipts and 3 in bottles migrates at low concentrations; dishwashing but not handwashing prior to use reduces bisphenol A (BPA) leaching from Tritan
