Problems solved by technology
At present, most of the disposable products that people use daily are petroleum-based plastics, which are cheap, but they are all products that are difficult to degrade. Due to the gradual increase in the use of these products in recent years, they have caused environmental pollution and affected the ecology. balance, more and more degradable plastic products are beginning to emerge, but the current degradable products always have one or another deficiency

Abstract
The invention relates to a biodegradable thermoplastic starch resin film. The composition and content of raw materials are as follows: thermoplastic starch 40-52%, metallocene 8-16%, low-density polyethylene 20-30%, smooth 3-5% of agent, 4-6% of high-density polyethylene, 5-8% of pigment; the preparation method of the biodegradable thermoplastic starch resin film comprises the following steps: mixing thermoplastic starch, metallocene, low-density polyethylene, smooth Agents, high-density polyethylene, and pigments are mixed by the mixer according to the above mass percentages, added to the film blowing unit, and plasticized, extruded, blown, drawn, and rolled by the blown film extruder, and then blown. Biodegradable thermoplastic starch resin film; Compared with the prior art, the present invention adopts special raw materials, such raw materials are green and environment-friendly bio-polyethylene, etc., so that the film produced can be biodegradable, bio-environmental, and reduce carbon dioxide emissions.
Description
[technical field] [0001] The invention relates to the technical field of degradable resin films, in particular to a biodegradable thermoplastic starch resin film and a preparation method thereof. [Background technique] [0002] With the gradual improvement of people's living standards, people's health awareness and awareness of environmental protection are increasing. At present, most of the disposable products that people use daily are petroleum-based plastics, which are cheap, but they are all products that are difficult to degrade. Due to the gradual increase in the use of these products in recent years, they have caused environmental pollution and affected the ecology. With the balance of the environment, more and more degradable plastic products are beginning to emerge, but the current degradable products always have one or another deficiency. Therefore, biodegradable materials (plastics) are an important part of environmental protection engineering. [Content of the ...
