Cereplast, Inc., manufacturer of proprietary bio-based, sustainable plastics, has secured patent protection for its Cereplast Compostable® resin family of products from the United States Patent and Trademark Office (USPTO). The U.S. patent (#7,393,590) was issued on July 1, 2008 and adds to the company's intellectual capital. This formulation patent strengthens the existing patent portfolio of Cereplast and protects the composition of Cereplast's Compostable resin grades designed primarily for extrusion coating resin on paper and other substrates.
Cereplast Compostables® resins are renewable, ecologically sound substitutes for petroleum-based plastic products, replacing nearly 100 percent of the petroleum-based feedstocks used in traditional plastics with renewable resources.
All Cereplast Compostables® resins are certified as biodegradable and compostable in the United States and Europe, meeting BPI (Biodegradable Products Institute) standards for compostability (ASTM 6400 D99 and ASTM 6868), and European Bioplastics standards (EN 13432).
