The classification of carton materials is as follows:

1. Whiteboard: Whiteboard is a kind of cardboard with a smooth white front and a gray background on the back. This kind of cardboard is mainly used for making cartons for packaging after single-sided color printing, or for designing and making products by hand.

2. Cowhide cardboard: Cowhide cardboard, called box board paper in China, is one of the main types of carton paper. Domestic cardboard is divided into three grades: excellent, first-class and qualified. Kraft paper must be tough in texture, with high bursting strength, ring crush strength and tearing strength, and also with high water resistance.

3. Corrugated base paper: Corrugated base paper is one of the important parts of corrugated board production. Corrugated base paper requires good fiber bonding strength, smooth paper surface, good tightness and stiffness, and certain elasticity to ensure that the manufactured carton has shock resistance and pressure resistance.
