What are the materials used for processing Corrugated Box
- By:Trade Bulgarian
Corrugated Boxes are generally made of corrugated cardboard with a peculiar structure. The structure of general corrugated cardboard is: a total of three layers, the middle is a zigzag thin cardboard, and the two sides are glued and wrapped with corrugated and flat thin cardboard. Such a structure can not only keep heat better, but also play a role in buffering and unloading force when being hit, and can play a role in increasing hardness when being squeezed. The packaged items in the packing box are not easily damaged during transportation or storage, thereby increasing the safety of the items. And because cardboard is mostly made of plant fiber as the main material, it has strong flexibility and is not easy to break, which increases the protection of articles.
1. White board paper has the characteristics of high folding resistance and stiffness. The surface of the white board paper is smooth, the front is white, and the back is generally gray cardboard. This kind of carton is mostly used for packaging handicrafts, small department stores, etc. White board paper has the characteristics of high folding resistance and stiffness, and is mainly produced in Japan, South Korea, and the United States.
2. Kraft cardboard, with properties such as wear resistance, pressure resistance, and water resistance. It is one of the main paper types in our country and belongs to high-quality paper types. Kraft paperboard has properties such as wear resistance, pressure resistance, and water resistance, and most of it is mainly used for packaging large objects in life.
3. Corrugated base paper has certain elasticity and pressure resistance. The index should be controlled, if the moisture is too small or too large, there may be cracks and soft paper, which will increase the processing cost. Finally, cartons of different materials will have different prices. When purchasing cartons, you should choose regular and reliable manufacturers. Buying in large quantities will be much cheaper and the quality will be good.
