Biodegradable plastic are widely used in various industries, and can be partly replaced by general plastics. The largest amount of use is environmental protection materials, packaging materials, and medical materials.

1) Agricultural use

The ideal agricultural material is the synergy of other biodegradable materials to transform into materials that improve soil quality. Biodegradable materials are mainly used as agricultural plastic membranes and crop growth containers in agriculture.

2) Packaging use

Food bags, packaging bags, and garbage bags made of biodegradable plastic are very popular due to their biodegradability. Biodegradable packaging materials generally add degradable polymer polymers to layer compression membranes or mixes directly with layer pressure materials. Food packaging materials and containers are generally required to ensure that foods are not rotten, oxygen isolates and materials are non -toxic. Among them, the most representative is polycaticate (PHB) and polycaticate (PHV) and its cluster (commodity name BIOPOL).

3) Medical biodegradable materials

Medical materials not only need medical effect, but also safe, non -toxic, non -irritating, and have good biocompatibility with the human body. Medical biodegradable materials refer to the decomposition of dissolved enzymes in the organism after completing the medical function. Biodegradable plastic has been widely used for surgical sutures, artificial skin, orthopedic surgery, drug-in -pharmaceutical slow release agent and absorption suture line Fields.
