Abstract

The invention discloses a high-toughness and wear-resistant paper packaging material and a preparation process thereof. Recycled waste paper fibers are used as a main body; rich hydrogen bonds in polyacrylamide are utilized to rearrange bacterial cellulose in the forming process, so that a bacterial cellulose and polyacrylamide composite material with higher toughness and a spiral structure is formed, and the toughness of the paper packaging material is effectively improved; a light click reaction between a carbon-carbon double bond in polyacrylamide and a thiol group is utilized, so that theadhesive force of a bacteriostatic agent is increased, and the bacteriostatic property of the paper packaging material is effectively improved; and a high-density polyethylene film is bonded through carbene glue, so that the wear resistance of the paper packaging material is improved in cooperation with bamboo fibers while water resistance and pollution resistance are achieved.

Description

technical field [0001] The invention relates to the technical field of paper packaging materials, in particular to a high-toughness, wear-resistant paper packaging material and a preparation process thereof. Background technique [0002] In recent years, due to the rapid development of the Internet business, the development of the logistics industry has been driven, and the demand for paper packaging materials for parcels has increased year by year, and the annual consumption of packaging materials has also increased significantly. However, although there are many types of existing packaging materials, their performance in terms of toughness and abrasion resistance still needs to be improved; in addition, paper packaging materials are also widely used in industries such as food and medicine, so the resistance of paper packaging materials also needs to be considered. At the same time, how to deal with the problem of water absorption caused by wet weather, which affects the qu...
