Paper corner protector

Abstract

The invention discloses a paper corner protector which comprises L-shaped paper substrates, wherein each L-shaped paper substrate is formed by integrally pressing a plurality of paperboards. Continuous square strips are evenly arranged on one side edge of each L-shaped paper substrate every other seam. The paperboards on each L-shaped paper substrate sequentially comprise a plastic layer, a honeycomb core paper layer, a compression resistance layer, a corrugated paper layer and a damp-proof layer from the upper surface to the bottom of the substrate. According to the paper corner protector, the compressive strength of the paper corner protector can be improved due to the compression resistance layers and the corrugated paper layers, the honeycomb core paper layers have the shock resistance and shock absorption functions, the arranged damp-proof layers have the water-proof and damp-proof functions, and the arranged plastic layers are capable of preventing packaged or supported objects from being scratched and damaged. Compared with the prior art, the paper corner protector has the advantages of being high in compressive strength, excellent anti-knock performance and damp-proof performance and long in service life. One side edge of each L-shaped paper substrate is provided with the square strips, and the paper corner protector has the advantages of being light in mass, safe and convenient to use and capable of saving materials.

Description

technical field [0001] The invention relates to the field of packaging materials, in particular to a paper corner protector. Background technique [0002] Paper corner protector, also known as paper wrap corner, corner protector cardboard, edge board, corner paper, paper angle steel, etc., is generally made of bobbin paper and kraft cardboard and pressed by a complete set of corner protectors. Its two ends are smooth and flat, without obvious The burrs are perpendicular to each other, can replace 100% wood for recycling, and have the obvious advantages of simple structure, light weight, firmness, environmental protection, and low cost. It is an ideal new green packaging material. Paper corner protectors can greatly reduce the damage suffered by the goods during transportation, thereby improving the external image of the product. According to different transportation methods and environmental conditions, they are widely used in the construction industry, steel industry, candy...

AI Technical Summary

Problems solved by technology

This kind of serrated L-shaped paper corner protector has the characteristics of easy packaging and material saving, but the top of the serrated teeth on the L-shaped body is sharp and hard, which is easy to scratch people during production or use, and is extremely unsafe

Moreover, this kind of paper corner protector has poor compressive and load-bearing strength, is easy to be brittle, and is easy to be damaged by moisture absorption.
