The classification of all -biological decomposition bags mainly include PLA, PBS, PBAT classes, and PHA classes, and their physical properties include melting points and mechanical properties.

全生物降解袋是环保材料的一个重要分支，它们按照不同的生物质原料和合成方式可以分为几个主要类别： The whole biological dismissal is an important branch of environmental materials. They can be divided into several main categories according to different biomass raw materials and synthesis methods:

1. PLA class (polystumin): Polymers synthesized by planting plant resources such as corn starch as raw materials.
2. PBS class (polyester): This kind of material has good biocompatibility and biodegradability, which is formed by aggregation of butanic acid and butanol.
3. PBAT class (polyester): combined with the advantages of PBT (polytic benzene dilate (diode diacerrin) and PBSA (polyteraxic acid/butanol symbol), which has good mechanical properties and ductility.
4. PHA class (polystroxyxate): A type of polymer material synthesized by microorganisms under specific conditions has good biodegradation and compatibility.

The physical properties of all -biological dislocation bags are the key factor that determines its applicability in actual application. These properties include:

1. Following point: refers to the temperature of the material from solid state to liquid, affecting the processing conditions and heat resistance of the material.

2. Mechanical properties: including tensile strength, broken elongation, etc., which is directly related to the durability and scope of the bag. Understanding these categories and physical properties is very important for choosing the appropriate all -biodegraded materials. It can not only meet the needs of environmental protection, but also ensure the stability and reliability of the product during use.
