Detailed Product Description

Biodegradable film extrusion machin;

Biodegradable plastic film is a new type of plastic film that can be biodegraded and will not pollute the soil. Biodegradable plastic film is a kind of plastic film that can cause degradation in natural environment. Microorganisms, such as bacteria, fungi and actinomycetes, attack plastic films. Due to cell growth, polymer components are hydrolyzed, ionized or protonated, resulting in mechanical damage and splitting into oligomeric fragments. Enzymes secreted by fungi or bacteria dissolve or oxidize water-soluble polymers into water-soluble fragments, forming new small molecule compounds until they are finally decomposed into C02 and H20.
Biodegradable plastic film is a new type of ground cover film, which is mainly used for ground cover to improve soil temperature, maintain soil moisture, maintain soil structure, prevent pests from attacking diseases caused by crops and some microbes, thus promoting plant growth.
There are many kinds of classification methods of biodegradable plastic film, which can be divided into the following types according to different classification methods:
1. According to the mechanism of degradation and the form of destruction, the biodegradable film can be divided into two types: the complete biodegradable film and the added biodegradable film.
The film is completely biodegradable plastic film can be completely decomposed by microbial composition, the material is mainly derived from starch, cellulose, chitosan and other natural polysaccharide material, the final product of the degradation of C02 and H20, was completely natural consumptive, does not produce secondary pollution to the environment two. The main varieties are polylactic acid (PLA), polyhexyl ester (PCL), polybutyrate acid ester (PUB) and so on. In addition, polyvinyl alcohol can be completely degraded by water and microbes.
The addition type biodegradable plastic film is made of natural or synthetic polymers or biodegradation promoters and processing aids, which are biodegradable on the basis of general plastics without biodegradability. At present, the addition type biodegradable film is mainly composed of general plastics, starch, compatibilizer, self oxidizing agent and processing aid. The typical variety is polythene starch biodegradable film.
2, according to the raw materials, bio degradable film can be divided into biodegradable starch based biodegradable plastic film, cellulose film, cellulose and other natural polymer blend and copolymerization of lignin based biodegradable plastic film, etc..
3. According to the molding process, the biodegradable film can be divided into thin film type, injection type, sheet type and foaming type
