Classification of biodegradable bag raw materials

In the early stage, biodegradable materials were mainly filled starch-degradable plastics, which can save some fossil resources and reduce carbon dioxide emissions.In terms of degradation performance, starch can be degraded, but the polyolefin polymerized with it cannot be degraded. It can only exist in nature as tiny particles, which fails to completely solve the white pollution and will still harm the ecological environment.

 One of the promising materials in the future is biodegradable material, which is completely biodegradable and does not pollute the environment, which is very beneficial to environmental protection, and is recognized as environmentally friendly material.

The main product of biodegradable material is PLA biodegradable material which is made of natural high polymer or natural monomer synthetic high polymer.

Polylactic acid (PLA) : degradation is divided into two stages: 1, the first is pure chemical hydrolysis into lactic acid monomer.2. The action of lactic acid monomer in microorganisms decreases and decomposes into carbon dioxide and water.Biodegradable bags can be decomposed into carbon dioxide and water in natural soil or industrial compost conditions for 180 days without polluting the environment.
