Depending on the materials used, there are corrugated cardboard boxes, single-layer cardboard boxes, etc., available in various specifications and models.

The commonly used types of cartons are three-layer and five-layer ones, while seven-layer ones are less frequently used. Each layer is composed of inner paper, corrugated paper, core paper and outer paper. The inner and outer papers can be made of tea board paper or kraft paper, while the core paper is made of corrugated paper. The colors and textures of various types of paper are different, and the colors and textures of paper produced by different manufacturers also vary.

The functions of corrugated cardboard formed by bonding corrugations of different wavy shapes also vary.

Even if the same quality of face paper and liner paper are used, due to the difference in corrugation shapes, the performance of the corrugated board formed will also have certain differences.

At present, the corrugation shapes commonly used internationally are divided into four types, namely Type A corrugation, Type C corrugation, Type B corrugation and Type E corrugation.

Corrugated cardboard made of type A flute has better cushioning performance and A certain degree of elasticity, while type C flute is inferior to type A flute.

However, its stiffness and impact resistance are superior to those of type A flute. The B-type corrugation has a high density of arrangement. The corrugated cardboard made from it has a smooth surface and high load-bearing capacity, making it suitable for printing. The E-shaped flute, due to its thinness and density, further demonstrates its rigidity and strength
