Technical Field

The invention relates to the field of packaging boxes, in particular to a corrugated paper packaging box.

Background

Corrugated paper packing box refers to a packing carton made of corrugated paper boards through die cutting, impressing, nailing or box bonding, the corrugated paper packing box is a packing product with the widest application, the using amount is always the first of various packing products, and the corrugated paper box gradually replaces a wood box and other transport packing containers with excellent using performance and good processing performance, becomes the main force of transport packing, not only protects commodities, is convenient for storage and transportation, but also beautifies commodities and publicizes commodities, belongs to a green and environment-friendly product, and is beneficial to environmental protection and loading and unloading transportation; however, the existing corrugated paper packing boxes are limited in waterproof function, and moisture is easily absorbed into the paper boxes, so that internal commodities are affected with damp; when stacking, common corrugated paper packing boxes are not provided with a mutual connection structure, and stacking is unstable; moreover, the interior of the corrugated paper packaging box can not be directly used for containing commodities, and an inner packaging box or a buffer object needs to be arranged independently, so that the use is inconvenient; to this end, we propose a corrugated paper packing box.
