Publication number: 20100003457Abstract: A layer of a biodegradable, compostable co-polyester is extrusion coated onto the surface of a bio-degradable compostable cellulose film to overcome the limitations of cellulose film as a packaging film for fresh produce and still retain the biodegradability, compostability and stiffness of the overall structure. Additionally, good bond strength between the cellulose film and the extruded co-polyester polymer is achieved by applying a thin coating of co-polyester to the surface of the cellulose film by means of a solvent or water based coating process. A biodegradable, compostable co-polyester polymer is extrusion coated onto an additional barrier layer to provide a significant barrier enhancement in high humidity environments beyond levels that would be reasonably predicted.Type: ApplicationFiled: June 30, 2009Publication date: January 7, 2010Applicant: AMCOR FLEXIBLES TRANSPAC N.V.Inventors: Peter Ettridge, Christopher R.
