What are the characteristics of fully biodegradable plastic bags?

1. What is a fully biodegradable plastic bag? 1,MaterialFully biodegradable plastic bags are made of biodegradable raw materialsPLA,PBATand corn flour are the key raw materials. 2,AdvantageDiscarded in the environment or retting, it will be degraded into carbon dioxide and water by surrounding microorganisms, and the general dissolution cycle is about one year. 3,performanceThe fully biodegradable plastic bag feels very soft and smells faintly fragrant, which is due to the production and processing of the masterbatchPBAT, the modifier is the raw material of corn flour, soThere is also a light corn fragrance. The raw material of fully biodegradable plastic bags comes from corn flour.Second, how to complete the degradation? It can be degraded naturally without special treatment, the reason is that there are degradable materials in the processed raw materials. PBATIt is actually a biodegradable raw material, and the production cost is lower, and it has good structural mechanical properties and biological safety performance.PBATThe production process is very complete, and the production equipment is relatively good. becausePBATIt is also a natural degradable raw material, and the fully biodegradable plastic bags produced and processed from it can also replace high-pressure polyethylene disposable packaging bags. The raw materials for the production and processing of fully biodegradable plastic bags are generally composed of five different raw materials, among which polyethylene terephthalic acid/Adipic acid/Butadiene and polylactic acid or tapioca plastic are cost-effective compositions.3. Degradation cycle time of fully biodegradable plastic bags: 1.In the geographical environment, that is, in the presence of sun, soil layers and water, the complete degradation cycle time is generally in the1year up and down; 2.Under the condition of composting, the degradation cycle time is about one year, and it is converted into carbon dioxide and water after complete degradation.
