Abstract

The invention provides nano eco-degradable plastic shopping bags with different specifications, which are prepared by adding nano eco-degradable plastic master batches to common plastics, wherein the proportion is 0.01-80% in percentage by weight. The invention also provides a production technology for preparing the nano eco-degradable plastic shopping bags.

Description

technical field [0001] The invention relates to a nano-ecologically degradable plastic shopping bag that can be degraded in the natural environment and a production process for preparing the nano-ecologically degradable plastic shopping bag. Background technique [0002] With the improvement of living standards and the acceleration of the pace of life, people's consumption patterns are increasingly becoming more convenient, efficient and hygienic. Under the guidance of this general trend, disposable plastic products such as plastic bags and plastic lunch boxes have increasingly penetrated into all aspects of people's daily life, becoming an indispensable part of consumers' fast-paced and efficient lives. [0003] But on the other hand, these plastic packaging materials are often discarded after use, and the non-degradability of waste plastics has caused "white pollution". In recent years, the situation of "white pollution" in my country has become increasingly serious, and ...
