Problems solved by technology

[0002] As a product that is frequently used in daily life, plastic bags are used in a large amount, and in actual use, they often need to be replaced after one use, thus causing a large amount of plastic waste, which is often used in practice. Due to its non-degradable nature during the treatment process, it has brought great pollution to the living environment
In the prior art, although degradable materials such as starch are used to make plastic bags, their tensile strength and elongation at break are often poor, which brings great inconvenience to daily use, and they are often not used up at one time. , it has been damaged and cannot be used, so not only the cost of use is high, but also the replacement is more frequent, resulting in a great waste of resources

Abstract

The invention discloses a degradable environment-friendly plastic bag and relates to the technical field of plastics. The degradable environment-friendly plastic bag contains a cetearyl glucoside modified biodegradation agent with the mass being 15-16% of the mass of the plastic bag. The degradable environment-friendly plastic bag has the advantages that by analyzing the structural characteristicsof polyethylene resin and adding a certain quantity of cetearyl glucoside modified biodegradation agent, the connecting structure between polyethylene resin molecules and other components can be improved evidently, the melt processability of the material system can be increased to a certain degree, the physical mechanical performance of the produced plastic bag can be increased, and the plastic bag is good in degradability and fast in degradation.

Description

technical field [0001] The invention belongs to the technical field of plastics, and in particular relates to a degradable environment-friendly plastic bag. Background technique [0002] As a product that is frequently used in daily life, plastic bags are used in a large amount, and in actual use, they often need to be replaced after one use, thus causing a large amount of plastic waste, which is often used in practice. Due to its non-degradable nature in the process of processing, it has brought great pollution to the living environment. In the prior art, although degradable materials such as starch are used to make plastic bags, their tensile strength and elongation at break are often poor, which brings great inconvenience to daily use, and they are often not used up at one time. , which has been damaged and cannot be used, so not only the use cost is high, but also the replacement is more frequent, resulting in a great waste of resources.
