Usage: Carton low cost, easy to package, suitable for adding fillers, clean and other suitable for product packaging, goods transportation, material finishing, etc.
The carton packing materials are usually made of cow cards made of American waste, because the foreign waste impurities are relatively small, the quality of the raw paper produced is better. Other materials include vermicelli, whiteboards, high strength tiles, corrugated tiles and so on. The raw paper or cardboard produced by different base paper manufacturers is different in terms of breaking resistance and other quality indexes.
1. Carton packaging refers to the packaging of products in the circulation process, in order to protect products, facilitate storage and transportation, and promote sales. Carton packaging is the most widely used packaging method.

2. according to paper quality, there are corrugated boxes, single cartons, etc. There are three layers and five layers in common use, seven layers are less used, each layer is divided into lining paper, corrugated paper, core paper, paper, surface paper has tea board, kraft paper, core paper corrugated paper, all kinds of paper color and feel are different, different manufacturers produce paper (color, feel) is also different. Corrugated corrugated cardboard with different corrugation has different functions. Even if the same quality of paper and lining paper, due to the difference in corrugated form, the performance of the corrugated board is also different. Their technical specifications and requirements are shown in Table.
3. Corrugated cardboard made of A-type corrugated has better cushioning property and certain elasticity, followed by C-type corrugated than A-type corrugated. But the stiffness and impact resistance are better than A-shaped corrugated; B-shaped corrugated board with high density, flat surface, high pressure, suitable for printing; E-shaped corrugated because of its thin and dense, but also presents its rigid strength.
