The global PBAT (polybutylene adipate terephthalate) market is expected to grow at a CAGR of 8.7% during the forecast period 2021 to 2031 with an end value of $2 billion, according to a report by Transparent Market Research. Fruit and vegetable intelligent packaging using PBAT-based biodegradable mulch films is used to reduce food waste. The films provide increased oxygen and water vapor transfer rates in fruit and vegetable bags.
PBAT is a strong, ductile material that can be manufactured using standard film extrusion procedures. This aids in the production of films having LDPE (low density polyethylene)-like mechanical characteristics. Compared with its homopolymers, however, PBAT is relatively rigid. As a result, adding PBAT to polymer blends, including brittle polymers, can help enhance toughness without compromising biodegradability.
