Bio-degradable plastic refers to a kind of plastic whose products can meet the requirements of use with various properties, remain unchanged during the storage period, and can be degraded into environmentally sound substances under natural environmental conditions after use. Therefore, it is also called environmentally degradable plastic.

There are many new types of plastics currently on the market: photodegradable plastics(film), biodegradable plastics(film), light, oxidized/biodegradable plastics, carbon dioxide-based biodegradable plastics, and thermoplastic starch resin degradable plastics.

The main application areas of degradable plastics are: agricultural mulch, various plastic packaging bags, garbage bags, shopping bags in shopping malls or supermarket, and disposable tableware, etc.

Evaluation standard:

The American ASTM has published the following test standards: relevant evaluation test standards for biodegradable plastics, ASTM D5209-92, ASTM D5210-92, ASTM D5247-92, ASTM D5271-92, ASTM D5338-92.

Related evaluation test standards for photodegradable plastics, ASTM D5071-91, ASTM D5208-91, ASTM D3826-92.

Environmental safety related evaluation test standards, ASTMD5152-91.

The relevant test standards published in China are as follows:

GB 18006.1-1999 "General technical requirements for disposable degradable tableware",

GB/T 18006.2-1999 "Test method for degradation performance of disposable degradable tableware",

HJBZ 12-2000 "Packaging Technical Requirements for Environmental Labeling Products for Products",

HBC 1-2001 "Technical Requirements for Environmental Labeling Products for Disposable Tableware",

QB/T 2461-1999 "Degradable Polyethylene Film for Packaging".

In the future, it is necessary to refer to the relevant test standards of developed countries in the world and China, combined with the market promotion of various products of degradable plastics, conduct in-depth research on the definition and evaluation methods of degradable plastics, and continuously improve and perfect the relevant test standards. This is the promotion of degradable plastics. The foundation and prerequisite of industrialization.
