Fully biodegradable plastic bag material - PBAT

Fully biodegradable plastic bag polymeric materials refer to plastic materials that can be degraded or decomposed through chemical, biological, or physical actions under the action of enzymes in microorganisms or plants and animals existing in nature, such as bacteria, fungi, and algae. Today, Shunxingyuan Packaging, a professional flexible packaging manufacturer, will take you to understand the materials of fully biodegradable plastic bags. PBAT.

Fully biodegradable plastic bag materials What kind of material is PBAT?

Among microbial synthetic biodegradable polymers, PLA is currently the most widely used microbial synthetic biodegradable polymer on the market; among chemically synthesized biodegradable polymers, polybutylene adipate-co-terephthalate (PBAT) is the most widely used. PBAT is mainly made from PTA (or DMT), AA, and BDO as raw materials, and is directly esterified and polycondensed under the condition of a catalyst, as shown in Figure 1-1. The mechanical properties and processing properties of PBAT are similar to those of LDPE, with good thermal stability, and can be processed by extrusion, blow molding, injection molding, etc. 。

and fully biodegradable plastic bag materials Unlike PLA, PBAT is a material with good toughness and high elongation but low strength. The Tg of PBAT is -30℃, the crystallization temperature is 110℃, the melting temperature is 130℃, and the decomposition temperature is 375℃. The aliphatic soft segment of PBAT has good degradation properties and can be decomposed by microorganisms in soil into CO2 and H2O, while the hard segment gives it excellent physical properties, heat resistance, and impact resistance.
