  • Patent number: 9994686
    Abstract: Disclosed are a biodegradable film and an enhanced biodegradable fabric and laminate prepared by laminated biodegradable films, which mainly comprise PBAT or PBS, or a mixture thereof, PLA and other degradable high molecular polymers, such as PBSA, PCL, PCL-BS and PHA, to prepare PLA, and a new mixture of PLA and PHAs, or a mixture of PLA with PBAT and PBS, or a mixture of PLA and PHAs with PBAT and PBS or other degradable high molecular polymers. The new fabrics and laminates have a stronger biodegradability in an environment containing microorganisms and have a good shelf life, and good strength, agility and flexibility.

  • Publication number: 20170073515
    Abstract: 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.
