Biodegradable bags are a new word for a large number of friends, and are now a new material packaging bag products on the market. But with so many popel looking for the bag, what's the appeal? Can keep everyone looking for it!
Biodegradable bags It is divided into two types, degradable and fully degradable：
Degradable: It is to add degradable masterbatch to traditional plastics to achieve partial degradation or accelerate the degradation effect.
Full degradation: It is a bag made of bio-based materials, which can be completely degraded in a certain time.
The raw material of the full biodegradable express bag is the use of bio-based material (PLA), which makes the express bag feel good and feel comfortable and soft; And can be used to compost after a certain period of time can be turned into fertilizer, is a green and environmentally friendly express bag. It not only plays a role in protecting the environment, reducing dependence on oil resources, but also beautifies our long-term living homes.
Polylactic acid (PLA) is a new type of bio-based and renewable biodegradable material made from starch derived from renewable plant resources (such as corn, cassava, etc.). Starch raw materials through saccharification to obtain glucose, and then from glucose and certain strains of fermentation to produce high purity lactic acid, then chemical synthesis method to synthesize a certain molecular weight of polylactic acid. It has good biodegradability and can be completely degraded by microorganisms in nature under specific conditions after use, generating carbon dioxide and water without polluting the environment, which is very beneficial to protecting the environment.
Polylactic acid has good thermal stability, processing temperature 170~230℃, and good solvent resistance; Products made of polylactic acid in addition to biodegradation, biocompatibility, gloss, transparency, feel and heat resistance is good, but also has a certain resistance to bacteria, flame retardant and UV resistance, so it is very widely used as packaging materials.
