Problems solved by technology

[0005] For a long time, the plastic film products we use are all disposable film products made of petroleum synthetic resins, such as polyvinyl chloride, polyethylene and other materials, which are discarded as garbage after use. It takes about 200 years to be decomposed, so some are discarded everywhere, causing a very harmful "white pollution", and some are buried or burned, which greatly wastes the oil resources that can only be formed in hundreds of millions of years. Harmful substances will be produced in the process of discarding plastic film products to directly pollute the air or water sources. Due to the non-degradable properties of petrochemical plastics, the residual plastics will destroy the soil structure, reduce the yield of many fertile fields, desertify the soil, block rivers, and cause floods.
[0006] In recent years, solving the harm of "white pollution" to human beings has been put on the agenda of many governments, and the voice is getting louder and louder. Countries have invested a lot of financial and material resources one after another, and have come up with corresponding control measures, but the effect None obvious

Abstract

A biodegradable resin and a preparation method thereof. The purpose of the present invention is to provide a film-blown biodegradable resin and a preparation method thereof. If the degradable plastic packaging film produced by this method can fundamentally solve the problem that the packaging material can be completely decomposed within 3 months to half a year after being discarded in nature or buried in garbage. Carbon dioxide and water, etc., are a fully biodegradable packaging material for substances that are beneficial to plant growth. Another object of the present invention is to be able to solve the problem of replacing the consumption of petroleum resources. The fully biodegradable material is a fully biological material and does not contain 4P (ie PE, PP, PVC, PS). It is a brand new biodegradable material that can effectively replace petroleum resources. Hundreds of millions of tons of polyolefin materials are used for packaging materials in the world every year, all of which are produced by cracking petroleum products. We have successfully made packaging materials based on starch, which will save a lot of oil resources for the country every year when oil prices continue to rise.
