Circulating utilization type packing material

Abstract

The invention discloses a circulating utilization type packing material. The circulating utilization type packing material is prepared from, by weight, 30-60 parts of starch, 10-30 parts of polylactic acid, 5-15 parts of plant fibers and 1-5 parts of vinyl / vinyl ketone copolymers. The circulating utilization type packing material has the advantages of availability to raw materials, high practical value, high strength, circulating utilization and degradability.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a recycling packaging material. Background technique [0002] Packaging products play a very important role in people's daily life and bring a lot of convenience to people's life, but most of the existing plastic packaging materials, such as plastic bags, polyethylene plastic foam, food packaging bags, etc. They are disposable, but they are degraded for too long after being discarded, which will bring many potential hazards to the environment: entering the soil will cause the soil to agglomerate, and when decomposed, a large amount of harmful substances will enter the soil and affect the growth of plants; Swallowed by animals may result in animal death and more. At present, some people use incineration or landfill methods for the convenience of disposal, which will cause air pollution or pollution of land and rivers. [0003] Although environmentally friendly recyclab...

[0002] Packaging products play a very important role in people's daily life and bring a lot of convenience to people's life, but most of the existing plastic packaging materials, such as plastic bags, polyethylene plastic foam, food packaging bags, etc. They are disposable, but they are degraded for too long after being discarded, which will bring many potential hazards to the environment: entering the soil will cause the soil to agglomerate, and when decomposed, a large amount of harmful substances will enter the soil and affect the growth of plants; Swallowed by animals may result in animal death etc.

At present, some people use incineration or landfill for the convenience of disposal, which will cause air pollution or pollution of land and rivers.

[0003] Although environmentally friendly recyclable high-strength bio-packaging plastics are also used to replace traditional plastics, many biodegradable plastics have been developed at home and abroad, but the price of these bio-packaging materials is very high, about 3-10 times the price of ordinary plastics. It limits the scope of its use, especially for our country, it is necessary to consider the comprehensive consideration of price and performance to manufacture biological packaging materials with excellent performance and low price
