What is 100% Biodegradable Material

    What is a biodegradable material and in which fields are it used? How do we distinguish this material?

    Starting in the 1970s, many countries began to develop completely biodegradable packaging materials. 

   Since polyolefin materials like PE and PP, which cannot be decomposed in a short period of time, Finally, through the research, the researchers synthesized a series of polyester materials that can be decomposed by microorganisms, and some green environmental protection materials extracted and synthesized from renewable resources (such as straw, bagasse, corn starch, etc.), and produced truly biodegradable packaging products.

    Biodegradable packaging must meet three conditions:

       1. It must be fully biodegradable to carbon dioxide and water ;

       2. Under industrial composting conditions, it must be completely degraded within 180 days;

       3. No toxicity and no harm to the environment after degradation.

   Biodegradable materials have been widely used to make a variety of food packaging products such as sugarcane pulp tableware, CPLA utensils, paper tableware, and fully degradable packaging bags, etc. These products can be treated in a composting factory and turned into organic fertilizers within 60to90days.Since the 1990s, western countries have been using disposable completely biodegradable tableware.

   At present, there are three widely recognized authentication marks for completely degraded material products in the world: "OK Compost", “Seedling” and "BPI".Therefore, if there is one of these several certification marks, then it can be identified as biodegradable products.
