With the emergence of biodegradable materials for plastic bags, many biodegradable plastic bag brands have appeared on the market, coming from different biodegradable plastic bag manufacturers. For some buyers who want to buy these plastic bags, they are definitely dazzled. I don’t know which one is better and which one is stronger?
Today, I will follow the editor to talk about what is called biodegradable material, and teach buyers how to identify good biodegradable plastic bag manufacturers.
Components of degradable materials
First of all, the biodegradable material is a relatively new type of polylactic acid. This material is a new type of biological substrate and renewable biodegradable material. The main reason is that glucose is obtained from starch raw materials through saccharification, and then fermented by glucose and certain strains to produce high-purity lactic acid, and then a certain molecular weight polylactic acid is synthesized by chemical synthesis. From here we can see that no chemical components were added during the evolution along the way, all of which were biological substrates, which laid the foundation for it to be biodegradable. Then added aliphatics, these two materials are put together to improve the toughness, biodegradability and molding processing properties of PLA.
Secondly, the most important thing to identify a good degradable plastic bag manufacturer is whether it has passed the national certification and approval of the manufacturer. Because our country has certain conditions for every manufacturer. Therefore, the quality of products produced by manufacturers with no products is often worrying. Especially from the outside, the degradable plastic bag is not very different from the previous traditional plastic bag. Therefore, some black-hearted businessmen are likely to be mixed with fish and eyes. After all, the traditional plastic bag production process is simpler. But if it is approved by the country, we can use it with confidence, and at the same time, we can also contribute to environmental protection!
