Abstract
The invention provides a degradable food packaging bag, relating to the technical field of packaging bags. The degradable food packaging bag is prepared from the following components in parts by weight: 20-45 parts of low density polyethylene, 25-40 parts of metallocene linear low density polyethylene, 15-35 parts of a polypropylene random copolymer, 5-15 parts of a calcium carbonate master batch, 10-20 parts of a stearic acid coupling agent, 1-15 parts of oxidized oil, 3-10 parts of a plasticizer, 2-8 parts of aucubin and 5-9 parts of an organic anti-sticking agent. By adding a reasonable compound additive, the prepared degradable food packaging bag can be reasonably, rapidly and naturally degraded, so that the environment-friendly performance of the degradable food packaging bag is remarkably improved, and the generation of a new pollution source is avoided.
Description
technical field [0001] The invention relates to the technical field of packaging bags, in particular to a degradable food packaging bag. Background technique [0002] Plastic packaging bags are consumables in daily life, and China consumes a large amount of plastic shopping bags every year. While providing convenience to consumers, plastic packaging bags have also caused serious waste of energy resources and environmental pollution due to excessive use and inadequate recycling. In particular, ultra-thin plastic shopping bags are easily damaged, and most of them are discarded at will, becoming the main source of "white pollution". More and more countries and regions have restricted the production, sale and use of plastic shopping bags. In order to build a resource-saving and environment-friendly society, my country has taken effective measures from the source to urge enterprises to produce durable and easy-to-recycle plastic shopping bags, guide and encourage the masses to ...
