Bing discusses in detail what biodegradable materials are and in what fields they are used? In China, with the implementation of mandatory garbage classification in the past two years, degradable materials have gradually become a hot concept. What are biodegradable materials and in what fields are they used? How can we identify this material?
The development of plastic packaging bags in a green direction is closely related to people's concern for environmental protection. Since the 1970s, many countries have begun to develop green plastic bags.
Since polyolefin materials mainly composed of PE and PP cannot be decomposed in a short period of time, scientists have finally synthesized a series of polyester materials that can be decomposed by microorganisms through research, as well as some green materials extracted and synthesized from renewable resources (such as straw, bagasse, corn starch, etc.), and produced truly biodegradable green plastic bags.
Degradable material packaging bags must meet three conditions: first, they must be completely degradable, and the products are carbon dioxide and water; second, under industrial composting conditions, they must be completely degraded within 180 days; third, after degradation, they do not produce any toxicity and have no impact on the environment.

Biodegradable materials have been widely used in customized packaging bags. Such packaging bags can be processed in composting plants and turned into organic fertilizers in 30-45 days. As early as the 1990s, Western countries have begun to use biodegradable shopping bags and kitchen waste bags.
