Environmentally friendly paper angle iron

Abstract

The invention discloses environment-friendly paper angle iron, which comprises an L-shaped angle iron body, wherein the L-shaped angle iron body comprises an outer surface layer, an inner surface layer and a middle layer, the middle layer is clamped and arranged between the outer surface layer and the inner surface layer, the outer surface layer and the inner surface layer are both waterproof PE (polyethylene) coated paper, a fireproof coating is also coated on the surface of the outer surface layer, a waterproof coating is also coated on the surface of the inner surface layer, the middle layer is high-intensity waterproof bobbin paper, and the middle layer is bonded with the outer surface layer and the inner surface layer through waterproof glue water. The environment-friendly paper angle iron has the advantages that each layer of the L-shaped paper angle iron body respectively has a waterproof function, the effective damp-proof and waterproof effects can be realized, the service life is prolonged, and the safety of inner package materials can also be ensured.

Description

technical field [0001] The invention relates to the technical field of packaging, in particular to an environmentally friendly paper angle iron. Background technique [0002] Paper corner iron, also known as paper corner guard and corner guard board, is made of bobbin paper and kraft cardboard. It is an ideal new green packaging material and meets environmental protection requirements. It has the characteristics of compression resistance, light weight and low cost. It can effectively protect the edges and corners of the product during handling, warehousing and transportation. It can be used with pallets to provide a firm overall package, prevent the goods from tilting and collapsing, and can enhance the stacking strength of the cartons to prevent packaging. damage to the product. Widely used in packaging and transportation of electronic appliances, high-tech products, furniture, flooring and other products. In order to achieve the waterproof effect, a waterproof layer is ...

AI Technical Summary

Problems solved by technology

In order to achieve the waterproof effect, a waterproof layer is applied on the outside of the angle iron, such as the Chinese utility model patent with the publication number CN2551595Y, a composite paper corner protector for metal packaging, which uses pulp as a raw material to make an "L"-shaped paper substrate corner protector , the inner side of the "L" type cardboard corner protector is coated with an anti-rust layer, and the outer side is coated with a waterproof layer to achieve waterproof and anti-rust functions, but only the outer side is coated with a waterproof layer, because it is very prone to friction during packaging and transportation and collision, the waterproof layer is easy to be broken, resulting in water immersion and damp phenomenon, which not only affects the service life of the corner protector, but also damages the inner packaging material
