WILSONVILLE, ORE. (Aug. 5, 12:20 p.m. ET) — Plastic bag, food container and cutlery manufacturer Trellis Earth Products Inc. has filed two new patents for bioplastics with the U.S. Patent Office.
One patent would cover a modification of the company's Trellis Classic-brand starch/hybrid blend. The Wilsonville-based firm claims the new blend, with 70 percent bio-based materials, has improved product qualities that include additional strength, higher biomass, lower cost, and greater formability.
Trellis' second patent application covers U.S. implementation of a next-generation bioplastic that uses agricultural byproducts such as wheat chaff and soybean hulls as feedstock.
The company claims its new material is waterproof and food-contact safe, yet is entirely petroleum free at a lower cost within existing polystyrene manufacturing infrastructure.
This blend is ideal for thermoforming trays and plates for compostable food service and conventional packaging applications, according to an Aug. 5 news release.
Both patent applications were filed on July 8, according to the release.
Founded in 2006, Trellis moved to its 33,000-square-foot plant in Wilsonville in May 2011. The company has announced plans to build a second plant in Illinois in 2012.
