What are the advantages of environmentally friendly lunch boxes and degradable plastic meals?
Degradable plastic refers to a plastic that is added to a certain amount of additives (such as starch, modified starch or other cellulose, photosensitizer, biodegradation agent, etc.) in the production process, which has reduced stability and is easily degraded in the natural environment. The advantage is: environmental sanitation - degradable plastic is generally considered to be a plastic that can be decomposed into low molecular substances by sunlight radiation or microorganisms in the soil. In addition to being degradable, it should be easy to process and satisfy the use. Required performance. The harmful effect of sunlight on polymer materials is the combined effect of ultraviolet light and oxygen, so it is called photooxidative degradation. In the case of polyolefins, photooxidation often causes chain scission or cross-linking of the polymer with concomitant formation of some oxygen-containing functional groups such as ketones, carboxylic acids, peroxides and alcohols. Its degradation mainly comes from the catalyst residues in the polymer, as well as the initiation of peroxide and carbonyl introduced during processing.
