Firstly, several confusing definitions and common misunderstandings related to biodegradable plastics are sorted out. Are bio-based plastics biodegradable plastics? Are petrochemical-based plastics not biodegradable plastics? The answer is all no. Next, let's briefly understand the concept analysis of biodegradable materials.

1. Bio-based plastics are not equal to biodegradable plastics:

Whether plastics are biodegradable or not has nothing to do with which raw materials the plastics are made of. Not all bio-based plastics are biodegradable, such as bio-based PET and bio-based PE are not biodegradable; while some petrochemical-based plastics, such as PCL, PBAT, etc., are biodegradable and belong to petrochemical-based biological Biodegradable plastic.

2. Biodegradable does not mean degradable in any natural environment:

Under the current technical conditions, the degradation rate of biodegradable plastics is relatively slow. In addition, biodegradable plastics need to be degraded in a special natural environment, which is not without conditions. Application of biodegradable plastics to disposable products At present, the most important application of biodegradable plastics is packaging products, accounting for nearly 60%. Packaging products are divided into rigid packaging and flexible packaging. Hard packaging includes boxes, bottles, etc., and flexible packaging includes packaging bags.

Most of the plastic packaging products are single-use, so we focus on the problems and challenges in the application of single-use biodegradable plastics. Common disposable plastic packaging products, plastic lunch boxes, tableware, plastic cups, packaging bags, express plastic packaging products...Under the New Plastic Restriction Policy, these disposable plastic packaging products will promote the use of degradable materials.
