TricorBraun Flex spent over two years developing the Biotre Film, an earth-friendly, heat sealable, barrier material. Biotre Film is made from 60% (by weight) renewable wood pulp. The wood pulp portion is biodegradable. Third party testing per ASTM tests D-6868 and D-6400 confirmed that nearly all of the wood pulp portion will disintegrate into healthy compost over 84 days in a backyard, home composting environment. The remaining 40% (by weight) of the bag is Polyethylene (PE) with an additive that is designed to make it disintegrate significantly faster than standard plastic.
The tin tie, degassing valve and labels are not compostable. Please remove before placing in home compost.
