Publication number: 20170073515Abstract: The invention relates to a novel biodegradable material prepared from PHA and PLA polymers, which can be used for manufacturing a blended product of PHA and PLA, and which can have accelerated biodegradation in a microorganic environment. The new product can be used for producing films, containers for solids and liquids, rigid or flexible packages, long-filament and short-fibre weaving, knitting and nonwoven fabrics, and composite products of fabrics, films and other materials by thermal forming, injection moulding or melt spinning. These blends also can have a long shelf life in a clean environment.Type: ApplicationFiled: November 23, 2016Publication date: March 16, 2017Applicant: U.S. Pacific Nonwovens Industry LimitedInventors: Cho Kee Wong, Larry Clifton Wadsworth
