Research on plastic in jars
Peer-reviewed journals, government agencies, and standards bodies.
“We found that food containers exposed to high-temperature released more than 10 million microplastics per mL in water.”
“All containers produced microplastics from 10 to 710 particles/L.”
NGO guides, independent testing, teardowns, and documented community reports.
“Glass bottles and jars with a plastic-coated metal closure may also shed microscopic bits of plastic, the study found.”
