Abstract

The invention relates to a preparation method of a paper bag and an environment-friendly paper bag, and the preparation method of the paper bag comprises the following steps: providing a raw paper base material, a pre-coating layer coating liquid and a barrier layer coating liquid; coating the pre-coating layer coating liquid on the surface of the raw paper base material; coating the surface of the raw paper base material coated with the pre-coating layer coating liquid with the barrier layer coating liquid to obtain the degradable paper bag; wherein the barrier layer coating liquid comprises an olefin polymer elastic dispersion which can be heat-sealed. By means of the method, the prepared environment-friendly paper bag replaces a traditional plastic bag, and environment pollution caused by plastic is reduced.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a method for preparing a paper bag and an environment-friendly paper bag. Background technique [0002] Due to the advantages of light weight, waterproof, durable, mature production technology, easy processing, and low cost, plastic products have been widely used in various fields around the world and are showing a growing trend year by year. [0003] However, these plastics that are discarded after use are not easy (or even impossible) to degrade, which seriously affects the appearance of the environment, and the components contained in them are potentially harmful, such as polystyrene, polypropylene, polyvinyl chloride and other polymer compounds. Plastic products such as packaging bags, cleaning bags, agricultural mulch films, disposable tableware, and plastic bottles are disposed of as solid waste after use. Due to random throwing and throwing, it is difficult to degrade and process,...
