What is advantage of biodegradable plastic bags?
Biodegradable Plastic Supermarket Bags are divided into two categories: direct contact with food and direct contact with non-food. These two types of products should be clearly marked on the shopping bag as "bBiodegradable Vegetable And Fruit Bags for direct contact with food" or "Biodegradable Promotional Plastic Bags for direct contact with non-food", and the executive standard, specification, load bearing, manufacturer, environmental protection and safety statement of the shopping bag should also be marked.
Biodegradable Promotional Plastic Bags used to manufacture Biodegradable Plastic Shopping Bags refers to a kind of plastic that can be degraded by natural microorganisms such as bacteria, molds (fungi) and algae. The ideal biodegradable plastic has excellent performance. After being discarded, it can be completely decomposed by environmental microorganisms, and finally become an integral part of the carbon cycle in nature. Biodegradable Vegetable And Fruit Bags can be completely degraded when buried in soil for 5 to 6 months under normal climatic conditions, and will not affect plants. Compared with traditional plastic packaging materials, the cost of biodegradable materials is slightly higher, but it has the advantages of green environmental protection, energy conservation and emission reduction, renewable raw materials and other advantages, which can solve the problem of "white pollution", reduce oil consumption and ease the pressure on petrochemical resources. Biodegradable Vegetable And Fruit Bags will provide sufficient alternative protection to curb "white pollution".
Biodegradable Plastic Supermarket Bags should have four elements: first, the material can be decomposed by microorganisms and converted into carbon dioxide; The second is that the material can decompose in the process of burying soil, without "white pollution"; Third, the residue of buried soil will not have a negative impact on the biological growth process; Fourth, it does not contain heavy metal residues.
