According to the different types of paper, there are corrugated cardboard boxes, single-layer cardboard boxes, etc. The commonly used cardboard boxes have three or five layers, while seven layers are less commonly used. Each layer is divided into inner paper, corrugated paper, core paper, and surface paper. The surface paper includes tea board paper and kraft paper, while the core paper uses corrugated paper. The color and texture of each paper are different, and the paper produced by different manufacturers (color and texture) is also different. The functions of corrugated cardboard bonded with different corrugated shapes also vary. Even if the same quality of face paper and inner paper are used, the performance of the corrugated cardboard formed by the difference in corrugated shape also varies to a certain extent.
