Green environmental protection bag and processing technology thereof

Abstract

The invention discloses a green environmental protection bag and a processing technology thereof. The green environmental protection bag comprises, in weight percent, 20%-30% of polyethylene, 10%-20%of acrylic resin, 10%-15% of linear polyethylene, 50%-65% of calcium carbonate powder, 1%-3% of inorganic powder, 1%-3% of high filling powder, 1%-3% of setting agents and 1%-5% of softening agents. The green environmental protection bag has the advantages of degradability, high temperature resistance, flame resistance, tasteless property, safety, sanitation and the like. Degradation time can be adjusted according to the proportion of the calcium carbonate powder and the polyethylene, the higher the polyethylene content is, and the longer the degradable time is. Compared with a traditional plastic bag, the environmental protection bag prepared by the method has the advantages that the degradation time is greatly shortened, and environmental protection functions are improved.

Description

technical field [0001] The invention relates to the technical field of green environmental protection bags, in particular to a green environmental protection bag and its processing technology. Background technique [0002] Plastic bags are essential items in people's daily life and are often used to hold other items. It is widely used because of its low cost, extremely light weight, large capacity, and easy storage, but it is banned from use and production in some countries because of the extremely long degradation cycle and difficult disposal of plastic bags. The use of biodegradable starch materials and natural fibers to prepare degradable plastic bags has become a research hotspot around the world. However, starch materials and natural fibers also have many problems while improving the degradable performance of plastics. On the one hand, they will cause a decline in their physical and mechanical properties, low mechanical properties, insufficient load-bearing pressure, a...

AI Technical Summary

Problems solved by technology

However, starch materials and natural fibers also have many problems while improving the degradable performance of plastics. On the one hand, they will cause a decline in their physical and mechanical properties, low mechanical properties, insufficient load-bearing pressure, and cannot be used and carried repeatedly. It is too strong and has poor compatibility with most general-purpose resins, resulting in a significant drop in the mechanical properties of the film and poor water resistance. On the other hand, natural fibers are less environmentally resistant than glass fibers. Poor properties, such as poor antimicrobial properties, hinder the wide application of plastics made from starch and natural fibers in the process of industrialization

[0003] At present, in the existing plastic bag manufacturing process, in order to improve the quality of plastic bags, chemical tougheners will be added to the produced plastic bags to increase the toughness of plastic bags, but too much chemical tougheners are difficult to degrade and will affect the environment. It has a certain impact, and the addition of chemical components also has certain side effects, which will have a certain impact on the human body and seriously affect people's lives.
