FAQ
Frequently Asked Questions
Yes, food-grade HDPE is widely considered safe for food and drink containers and is approved by regulatory bodies like the FDA and EFSA.
Yes, it is one of the most commonly recycled plastics, designated by the resin identification code '2' (HDPE).
HDPE has a more linear molecular structure, making it stronger, more rigid, and less transparent than the more branched and flexible LDPE.
Common applications include plastic bottles, piping, geomembranes, plastic lumber, and containers for chemicals and detergents.
