The degradation of raw materials directly affects the production and production costs of biodegradable garbage bags of manufacturers; it directly affects the user's experience and cost of use. At present, the principles of classification of degradable materials are mainly distinguished from their sources. One is bio-based degradable materials, and the other is petrochemical-based degradable materials.

There are more than 10 kinds of biodegradable materials, which are also obtained according to different "production methods", including direct synthesis, secondary synthesis, and mixed synthesis. For example, thermoplastic starch, biocellulose, polysaccharides, PLA, PHA, etc. Petrochemical-based degradation materials are also divided into various types, all of which are synthesized after polymerization of petrochemical product monomers.

For example, PBAT, PBS, PPC, PGA, etc. Degradable garbage bag manufacturers use different degradation materials, the proportion of input, production technology, etc. will affect the quality, cost, and degradation speed of the product after use. We do not comment on how manufacturers choose biodegradable materials and how to produce them.

It is only recommended that users, when choosing degradable garbage bags, look at the manufacturer's strength, "wind evaluation", degradable test report, and price. The longer the manufacturer operates, the more attention it pays to customer experience, the tighter the product quality, and the basic manufacturing materials can "cut corners".
