Brief description of completely biodegradable plastic

Completely biodegradable plastics: Completely biodegradable plastics are mainly made of natural macromolecules (such as starch, cellulose, chitin) or agricultural and sideline products through microbial fermentation or synthesis of biodegradable macromolecules, such as thermoplastic starch plastics, aliphatic polymers Ester, polylactic acid, starch/polyvinyl alcohol, etc. belong to this type of plastic.

Brief description of technical features

1. In the biodegradable formula, all fully biodegradable components are used, so that the product can be 100% biodegraded after use and discard, and finally carbon dioxide and water are generated;

2. Starch, PLA, PVA (polyvinyl alcohol) have good compatibility, and a variety of natural additives are added to make the performance of the product approach or exceed the performance of ordinary plastics;

3. The production of this product has formed a unique technological process during the entire process of mixing, granulating, extrusion, blow molding, etc., which can continuously and stably carry out industrial production.

In the past ten years, plastics have penetrated into all walks of life and entered tens of thousands of households with their convenience, and brought huge environmental pollution. International and domestic environmental protection policies, copyrights, laws and regulations, and environmental protection bills have been promulgated one after another. It proves that the demand for biodegradable plastics is gradually entering normalization and industrialization, and the development of biodegradable plastics is entering a golden period of vigorous development.

PLA has stable performance during use. After use, it can be decomposed into carbon dioxide and water by microorganisms or enzymes in animals and plants in compost, soil, water and activated sludge. It has good biocompatibility and bioabsorbability. Sex and environmental friendliness is a good way to eradicate the "white pollution" caused by traditional plastics.
