Precision Color Graphics Ltd., a petfood packaging company, earned Biodegradable Products Institute certification for its Ecoterah petfood pouches and bags.

The Ecoterah multi-layer pouches and bags for petfood can contain several paper layers, a water-based adhesive and a biopolymer sealant. The inner film is made with an earth-friendly alternative to petrochemical-based films, and the carbon-neutral biopolymer is made with 100 percent annually renewable plant resources, according to the company.

The certification assures that the Ecoterah packaging products meet American Society for Testing and Materials D6868 and D6400 compostability standards. The Biodegradable Products Institute promotes the use and recycling of biodegradable polymeric materials via composting, and certification is awarded after third-party laboratory testing.
