What is Corrugated Plastic?

Corrugated paper is a board formed by gluing a tissue paper and a corrugated corrugated paper formed by corrugating stick processing. Generally, it is divided into two types: single corrugated cardboard and double corrugated cardboard. According to the size of the corrugated cardboard: A, B, C , E, F five types. The invention and application of corrugated paper have a history of more than 100 years. It has the advantages of low cost, light weight, easy processing, high strength, excellent printing adaptability, and convenient storage and transportation. More than 80% of corrugated paper can be recycled and recycled. Corrugated paper It can be used as packaging for food or digital products. It is relatively environmentally friendly and widely used.

Corrugated paper is a board-shaped object made of corrugated paper and corrugated corrugated paper formed by corrugated stick processing. Generally, it is divided into single sheets.

A-type corrugation and B-type corrugation are generally used for shipping outer packaging boxes, and beer boxes are generally made of B-corrugations. E corrugated is mostly used as a single-piece packing box with certain aesthetic requirements and content of appropriate weight. F-type corrugations and G-type corrugations are collectively referred to as

Corrugated	Corrugated height mm	/ 30cm	Plane pressure intensity	Vertical pressure intensity	Parallel pressure intensity	Cushioning	characteristic
A corrugated	4.5 ~ 5.0	32 ~ 36	can	excellent	can	excellent	Highest compressive strength, but easy to be damaged, flexible and cushioning, used for outer carton, grid
B flute	2.5 ~ 3.0	46 ~ 50	excellent	can	excellent	can	Poor strength, but good stability, flat surface, high surface pressure, suitable for printing, used for cartons, boxes, grids, linings
C flute	3.5 ~ 4.0	36 ~ 40	good	good	good	good	The intensity is between A and B, the price is more economical, and it is more common in mainland China
E flute	1.1 ~ 1.4	92 ~ 100					Thin and dense, light weight and good cushioning, cheap price, good printing effect, only suitable for fine inner packaging, not suitable for outer packaging and cushioning material.

As far as corrugated printing is concerned, nothing special

Corrugated paper is pressed into a corrugated shape during the production process. After it is made into corrugated paperboard, it will provide paperboard elasticity, flat compression strength, and affect properties such as vertical compression strength. Corrugated paper has a flat surface and the same thickness. There must be no paper diseases such as wrinkles, cracks, and holes, otherwise it will increase the breakage of the production process and affect the product quality.
