Poly(butylene adipate-co-terephthalate) (PBAT), also known as polybutyrate, is a semi-aromatic, biodegradable thermoplastic copolyester that can be easily molded and thermoformed. PBAT has many attractive properties that are similar to Hpolyethylene. For example, it has relative high elongation at break (30 - 40%) as well as moderate high impact and puncture toughness,and good biodegradability. PBAT blended with PLA or other degradable materials can be made into shopping bags, courier bags, agricultural munching film, food packaging box,knives and forks, straws and other biodegradable products
