Biodegradable lunch boxes generally refer to food containers made of biodegradable plastic, biodegradable pulp, biodegradable small molecule materials. Currently, more materials are used: PLA (polylactic acid), plant fiber (wheat straw pulp, sugar cane pulp, bamboo pulp), corn starch-based materials.
Biodegradable plastics do not degrade completely and still cause pollution. Some biodegradable plastics are left with a "skeleton" after their components are degraded or consumed by microorganisms. Although these plastic residues are not in the form of large pieces like non-degradable plastics, they only exist in nature as small particles, which still have an impact on the environment and soil.
For example, the "biodegradable polystyrene fast food box" developed by Shanghai Sanlin Degradable Resin Products Company can only reach 80% degradation to carbon dioxide and water in 200 days, 20% is still powder, small particles suspended in the air to cause environmental pollution, and the residual debris can loosen the clay soil, but excessive aggregation will directly lead to Soil "sanding".
Main components and advantages of disposable biodegradable pulp molded lunch box.
(1) The raw material is waste paper pulp or renewable straw fiber such as wheat, reed, straw, bamboo, sugar cane, palm, etc., which is widely available and inexpensive and does not use wood at all.
(2) No waste water is produced in the production process, no external discharge.
(3), the product is waterproof and oil-proof.
(4), the use of the process can be frozen, refrigerated, microwave heating, can be 220 degrees baking.
(5), the product can be completely degraded in the natural state within 45-90 days, home composting, the main component of the degradation is organic matter, will not produce any waste residue and pollution.
(6), as a packaging container with buffering, pressure resistance, shockproof, etc., can effectively protect the packaged products.
(7), packaging electronic products will not generate static electricity.
