Degradable lunch boxes generally refer to food containers made of degradable plastic, degradable pulp, and degradable small molecule materials. Currently widely used materials are PLA (polylactic acid), plant fiber (wheat straw pulp, sugar cane pulp, bamboo pulp), corn starch and so on.
Biodegradable plastics cannot be completely biodegradable utensils degraded and still cause pollution. After certain components of the biodegradable plastic are degraded or swallowed by microorganisms, the "bone" remains. Although these plastic residues do not exist in the form of large, non-biodegradable plastics, they can only become small particles in nature, which have an impact on the soil environment.
"Biodegradable polystyrene fast food box", 80% of it will be degraded into carbon dioxide and water within 200 days, 20% is still powder, small particles are suspended in the air, which causes pollution to the social environment, and the debris is time The hardened clay resources can be loosened, but excessive agglomeration will have a direct impact and lead to the "sandification" of our soil.
The main components and advantages of the disposable biodegradable pulp molded lunch box:
(1) The raw materials are waste paper pulp products or can be made of recycled wheat, reed, rice straw, bamboo, sugar cane, palm and other straws for fiber. The sources can be wide and the price is low. Chinese wood is not used at all.
(2) No wastewater is discharged during the production process.
(3) The product is waterproof and oil-proof.
(4) It can be frozen or frozen during use, can be heated in a microwave oven, and can be baked at 220 degrees.
(5) The product design can be completely degraded within 45-90 days under natural environmental conditions, and can be composted at home. After degradation, the main economic component is organic matter, and it will not develop any waste residue and pollution.
(6) As a Chinese packaging container technology, it has the characteristics of cushioning, compression resistance, shock resistance, etc., and can protect the packaged products through effective information.
(7) The development of packaging electronic technology products will not generate static electricity.
Different disposable lunch boxes require different proportions of raw materials, and generally manufacturers will issue product quality inspection reports.
