PBi spent over two years in developing the Biotrē Film, an earth friendly, heat sealable, barrier material. PBi conducted extensive cupping tests with industry leaders to verify that Biotrē protects products in the same way that a standard plastic/foil laminate material does. 

Independent laboratory analysis by Advanced Materials Center, Inc. (Ottawa, IL) has confirmed Biotrē performance.

Give us a call for further information on the analysis.

How does Biotrē  work?

Biotrē 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.

Biotre is not compatible with industrial or municipal composting.  It is best disposed by placing it in a privately managed compost pile where the 40% PE layer and one-way degassing valve can be removed manually and disposed in the regular trash.  When a portion or all of Biotre is properly disposed with regular trash, its impact on the environment will be much less compared to a standard plastic/foil material which is made from 100% non-renewable resources and is not considered biodegradable in any way.
