Introduction to corrugated cardboard

Corrugated paperA board is a multi-layer adhesive body composed of at least one layer of wavy core paper interlayer, which has good elasticity and elongation. Corrugated cardboard is made and produced from corrugated paper as the material. Let's have the editor from China Paper Industry Network introduce it to you:

Corrugated cardboard and high-strength corrugated cardboard, with high strength, are made from hanging surfaces纸A board like material formed by bonding high-strength corrugated paper formed by processing with corrugated sticks, consisting of surface paper, inner paper, core paper, and corrugated paper processed into corrugated waves. Solved some problems such as: in existing technology, flat or vertical placement is prone to deformation, bending, and poor compressive strength. As a new type of composite board that replaces wood with paper, it is mainly suitable for the production of packaging boxes, furniture, etc. There are colors such as colorful, rainbow, and metallic E-pits.

The common raw materials for high-strength corrugated paper now include cotton straw, rice straw, reeds, etc

In general, compared to the other two, the load-bearing capacity of a single layer of medium strength corrugated paper is 10kg, while that of high-strength corrugated paper is above 12kg.

There are still similarities between the two:

1. It is a board like material formed by bonding hanging paper and corrugated paper formed by processing with corrugated sticks. It is generally divided into two types: single corrugated cardboard and double corrugated cardboard, and is divided into five types according to the size of the corrugated: A, B, C, E, and F.

2. The invention and application of corrugated paper have a history of more than 100 years, with advantages such as 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 it can also be used as packaging for food or digital products, with a wide range of uses and relatively environmentally friendly.
