Regenerated garbage bag prepared from waste plastics and preparation method thereof

Abstract

The invention discloses a regenerated garbage bag prepared from waste plastics and a preparation method thereof. The garbage bag is prepared from the following materials in parts by mass: 30-70 parts of regenerated high-density polyethylene; 0-40 parts of high density polyethylene; 0-20 parts of regenerated low density polyethylene; 0-20 parts of low density polyethylene; 10 -30 parts of linear low density polyethylene; 0-8 parts of color master batch; and 1-5 parts of an opening master batch. The regenerated garbage bag is prepared from the waste plastics in the household garbage, so that the recycling of waste plastic resources is realized, the problems of plastic pollution and plastic resource consumption can be solved to a certain extent, and certain environmental friendliness is realized; and meanwhile, the waste plastic raw materials are wide in source and low in price, so that the cost is low and the waste plastic raw materials are easily accepted by the market when used for preparing regenerated garbage bags.

Description

technical field [0001] The invention relates to a recycled garbage bag and a preparation method thereof, in particular to a recycled garbage bag prepared from waste plastics and a preparation method thereof, belonging to the field of resource utilization of waste plastics. Background technique [0002] The proportion of plastic in domestic waste is generally 10% to 18%, and in some areas it is as high as 20%, of which 42% to 57% are PE plastic packaging products. In my country, the current annual production of waste plastics has exceeded 30 million tons, and continues to grow at a rate of 10% per year. However, its recycling rate is less than 30% of the production, and there is still a certain gap compared with developed countries. In order to improve the utilization efficiency of waste plastic resources and at the same time strengthen the pollution control of waste plastics, the country has successively implemented waste classification policies and plastic restriction order...

AI Technical Summary

Problems solved by technology

This method provides a way of resource utilization of waste plastics, but the prepared garbage bags need to be partially degraded under certain conditions, and some non-degradable plastic fragments will still remain in the environment after degradation, and the resulting plastic pollution is even worse. intractable

This kind of degradable garbage bag has no recycling value after being discarded, and it is difficult to degrade in the natural environment, which will bring new environmental problems
