Plastic packaging bag

Abstract

The invention relates to a plastic packaging bag and belongs to the field of processing of plastic products. The plastic packaging bag is prepared from raw materials in parts by weight as follows: 45-65 parts of polyhydroxybutyrate, 22-35 parts of polyvinyl butyral, 13-20 parts of polyethylene, 8-17 parts of chitosan, 12-20 parts of starch, 6-11 parts of lignin, 5-12 parts of cotton-linen fiber, 6-11 parts of montmorillonoid, 1-3 parts of a stabilizer, 2-4 parts of a coupling agent and 1-5 parts of a plasticizer. The plastic packaging bag is mainly prepared from bio-degradable polyhydroxybutyrate and polyvinyl butyral matched with chitosan, lignin, cotton-linen fiber and montmorillonoid, the toughness of the plastic packaging bag is guaranteed, the plastic packaging bag has a good degradation effect and influence on surrounding environment is reduced. The processing process is simple, convenient and low in manufacturing cost and has good economic benefits.

Description

technical field [0001] The invention belongs to the field of plastic product processing, and in particular relates to a plastic packaging bag. Background technique [0002] In people's daily life, plastic bags are often used to hold other items, and are widely used because of their cheapness, light weight, large capacity, and easy storage. Plastic bags are usually polymer compounds made of monomers as raw materials through addition polymerization or polycondensation reactions. They are generally made of synthetic resins and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. . But the "white pollution" caused by discarded plastic bags is also becoming more and more serious. With the strengthening of people's awareness of environmental protection, how to alleviate white pollution has become a topic of increasing concern, and more and more countries and regions have restricted the production, sale and use of plastic packaging bags.
