Abstract

The invention discloses a low pollution plastic shopping bag. The low pollution plastic shopping bag is prepared from, by mass, 75 to 80 parts of polycaprolactone; 15 to 20 parts of microcrystalline cellulose; 5 to 10 parts of a biodegradation aid; 2 to 3 parts of a dispersant; 1 to 1.5 parts of a photodecomposition agent; 1 to 2.5 parts of paraffin; 5 to 12 parts of chitosan; 12 to 18 parts of polylactic acid; 5 to 8 parts of konjac glucomannan; 4 to 10 parts of diatomite; and 3 to 6 parts of calcium carbonate. The low pollution plastic shopping bag can be degraded rapidly; processing periodis short; and environment pollution and damage can be reduced effectively.

Description

technical field [0001] The invention relates to an environment-friendly plastic bag, in particular to a low-pollution plastic shopping bag. Background technique [0002] Plastic bags are bags made of plastics such as polyethylene, polypropylene, polyester, nylon, etc. as the main raw materials. They are indispensable items in people's daily life and are often used to hold other items. It is widely used because of its cheap, extremely light weight, large capacity, and easy storage. However, due to the extremely long degradation cycle and difficult disposal of plastic bags after use, they cause great pollution to the environment, so their production and use are banned by some countries. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention discloses a low-pollution plastic shopping bag, which can be degraded quickly, has a short processing period, and effectively reduces pollution and damage to the environment. ...
