Material properties of biodegradable lunch boxes

1 The number of carbon atoms in the molecule of an organic compound decreases and the molecular weight decreases. 2 The macromolecules of the polymer compound are broken down into smaller molecules. 3 Plastic degradation: The term plastic degradation refers to the end of the life cycle of high molecular polymers. Plastic degradation is to reduce the molecular weight of polymers and the physical properties of polymer materials (plastics). Typical manifestations are: plastics become brittle, cracked, softened, hardened, and lose mechanical strength. The aging and deterioration of plastics is a degradation phenomenon. However, it takes decades or hundreds of years for general plastics to degrade into environmentally sound (less harmful) fragments or into CO2 and water, and return to natural circulation. Therefore, rapid degradation technology is now used to select easily degradable high-polyhydrocarbons and organics to make plastics to prevent pollution.
