PBAT is a new type of biodegradable and environmentally friendly material. In the field of polymer materials, it is a chemically synthesized biodegradable material. PBAT products can be used to manufacture degradable plastic products, including compost bags. Garbage packaging, shopping bags, electronic packaging, plastic film, catering equipment, golf studs, foam materials, etc. The synthetic raw materials for PBAT products can come from both petroleum resources and biological resource fermentation. Among them, PBS and PBAT are leaders in biodegradable plastic materials.

PBAT produced by Unilong Industry Co., Ltd. is a thermoplastic biodegradable plastic, a copolymer of butylene Adipic acid and butylene terephthalate, which has the characteristics of both PBA and PBT.

PBAT products have excellent comprehensive performance and reasonable cost-effectiveness. It is mainly used in: films for fully degradable packaging, fully degradable packaging bags (shopping vest bags, coiled Bin bag, pet excrement bags, electronic product packaging bags, food packaging bags), agricultural mulch films, etc.

Features and Benefits

PBAT products have excellent mechanical properties, close to PP and ABS plastics; Compared with biodegradable plastics such as polylactic acid, Polyhydroxyalkanoates, Polycaprolactone, etc., it has excellent mechanical properties, good heat resistance, and hot deformation temperature close to 90 ℃, which is the focus of research and development of biodegradable plastics at home and abroad.

PBAT has good processing characteristics and can be used for various molding processes on existing plastic processing equipment. At the same time, it can blend a large amount of fillers such as calcium carbonate and starch to reduce material costs;

PBAT products only undergo degradation under specific microbial conditions such as composting and water contact, and their performance is very stable during normal storage and use.


25kg aluminum bags, each 20 ‘container can hold 17mt of 800kg aluminum bags, and each 20’ container can hold 16mt The temperature during transportation and storage should not exceed 70 º C.
