Technical Field

The invention relates to the technical field of corrugated paper, in particular to novel high-strength waterproof corrugated paper and a preparation method thereof.

Background

Corrugated paper is a plate-shaped object formed by bonding corrugated paper of corrugated shapes formed by processing of liner paper and corrugated rollers, generally divided into single corrugated paper boards and double corrugated paper boards, and divided into the following two types according to the size of the corrugated paper: A. b, C, E, F, the invention and application of the corrugated paper has more than one hundred years history, and has the advantages of low cost, light weight, easy processing, large strength, excellent printing adaptability, convenient storage and transportation, etc., more than 80% of the corrugated paper can be recycled, the corrugated paper can be used as the package of food or digital products, and is relatively environment-friendly and widely used;

the A-type corrugated and the B-type corrugated are generally used as outer transport packaging boxes, beer boxes are generally made of the B-type corrugated, the E-type corrugated is mostly used as a single packaging box with certain aesthetic requirements and suitable weight of contents, the F-type corrugated and the G-type corrugated are collectively called as micro-type corrugated, and the micro-type corrugated is an extremely thin corrugated and is used as a disposable packaging container for foods such as hamburgers, cream fillings and cakes, or is used as a package for micro-electric products such as digital cameras, portable combination audio and the like and refrigerated goods.

However, the overall operation strength of the existing corrugated paper is still weak, and the situation of frequent damage and edge starting at the edge still occurs during the use operation, so that the basic operation requirement at the time is met, but the stability of the corrugated paper at the later stage is easily reduced, the service life of the corrugated paper is shortened, and meanwhile, the situation that the corrugated paper is affected with damp is easily caused due to the reduction of the overall operation strength, so that the overall waterproof effect is also reduced.
