Problems solved by technology

[0002] Existing plastic products are widely used because they are economical, practical, and easy to process. However, due to their own nature, traditional general-purpose polymer materials are difficult to be degraded by microorganisms, that is, they will not rot and mildew, which will lead to long-term retention in existing life.

Abstract

The invention relates to a biomass polyethylene film and a preparation method thereof, which is characterized in that plant fiber powder, polyethylene and auxiliary agents are used. The product of the invention is non-toxic and can be used for agricultural film, food packaging, disposable plastic products in daily life and the like. This product can be partially degraded by microorganisms in the natural environment, which overcomes the environmental pollution problem caused by the existing general-purpose plastic waste.

Description

technical field [0001] The invention relates to the technical field of film production, in particular to a biodegradable plant fiber powder-polyethylene film and a preparation method thereof. Background technique [0002] Existing plastic products are widely used because they are economical, practical, and easy to process. However, due to their own nature, traditional general-purpose polymer materials are difficult to be degraded by microorganisms, that is, they will not rot and mildew, which will lead to long-term retention in existing life. . Therefore, the pollution problem of plastic garbage bags is becoming more and more serious, which has attracted widespread attention all over the world. [0003] Add a certain proportion of natural fiber materials that can be degraded by microorganisms to the existing general-purpose polymer materials that cannot be degraded by microorganisms, such as rice husk powder, straw powder, corn cob powder and wheat flour, etc., to obtain pr...
