Abstract

The invention discloses an anti-falling and anti-deformation paper packaging box and a preparation process thereof. The packaging box is formed by hot-pressing bonding of an outer layer, an outer sponge, a middle layer, an inner sponge and an inner layer, the outer layer and the inner layer are formed by dipping and hot-pressing of carbon fibers and kraft paper with increased surface active groupsafter surface grafting polyurethane treatment, the outer sponge and the inner sponge are high-concentration polyurethane sponges and have good energy absorption and recovery capacity, and the middlelayer is prepared by blending and modifying high-density polyethylene, compatibilizers, thermoplastic polyurethane and light calcium carbonate. The packaging box has tensile, anti-falling and anti-deformation capabilities, so that a box body and articles in the box body can be more effectively protected.

Description

technical field [0001] The invention relates to the technical field of paper products, in particular to a drop-resistant and deformation-resistant paper packaging box and a preparation process thereof. Background technique [0002] With the rapid development of China's economy, the improvement of people's living standards and the increase of medical expenses caused by the aging population, the development of new drugs is intensified, the pace of reform of the medical security system is accelerated, and the expansion of medical insurance for urban residents, the industry will continue to maintain a rapid pace. growing momentum. In addition, the quality of Chinese packaging materials and the variety of packaging boxes are significantly lower than the international level. According to the survey, in developed countries, packaging accounts for 30% of the product value, while in China it is less than 10%. The next few years will be a period of rapid development of China's packa...
