Problems solved by technology

Plastic bags do bring convenience to people's lives, but the convenience at this moment brings long-term harm.
At present, although there are many researches and reports on degradable plastics, many specific problems cannot be solved. The load-bearing capacity of degradable plastic bags is low, which cannot meet the requirements of customers for loading more things and repeated use. The cost of degradable plastic bags is relatively high, and the temperature resistance The performance is not good, and the degradability is not good enough

Abstract

The invention discloses a high-strength easily degradable polyethylene plastic bag which is prepared from the following raw materials in parts by weight: 100 parts of linear low density polyethylene, 10-15 parts of modified ultra high molecular weight polyethylene, 25-35 parts of butyl acrylate grafted nano calcium carbonate, 30-40 parts of reed charcoal, 10-15 parts of polylactic acid, 5-10 parts of potato starch, 3-6 parts of glucose, 15-25 parts of a lignocellulose aerogel, 1-2 parts of polyethylene wax and 1-2 parts of a silane coupling agent. The high-strength easily degradable polyethylene plastic bag disclosed by the invention is low in manufacturing cost, good in integral strength and good in temperature-resistant property, and can be quickly degraded in a natural environment.

Description

technical field [0001] The invention relates to a plastic bag, in particular to a high-strength easily degradable polyethylene plastic bag. Background technique [0002] Plastic bags are daily necessities in people's lives. They are generally made of polymer compounds such as polystyrene, polypropylene, and polyvinyl chloride. China consumes a large amount of plastic bags every year. However, due to the excessive use of plastic bags and the low recycling value of plastic bags, the recycling of plastic bags is not in place, resulting in a great waste of resources. The molecular structure of plastic bags is stable, and it is not easy to be degraded by microorganisms in the natural environment. After long-term accumulation, the discarded plastic bags have caused huge pollution to the environment and caused great harm to the living environment of human beings. [0003] At present, China's annual output of plastics is 3 million tons, and its consumption is more than 6 million to...
