As an indispensable part of modern logistics, packaging cartons bear the important responsibilities of containing, protecting products and appearance. Corrugated cardboard is made of corrugated paper processed into corrugated corrugations by bonding face paper, lining paper and core paper box, and then made into cartons. Commonly used cartons are three-layer, five-layer and seven-layer.

[0003] In actual use, the carton is initially in an extended state, then folded into a three-dimensional shape, the bottom is pre-bonded with tape, the items are placed inside the carton, and finally the top of the carton is bonded with tape to complete the packaging of the goods.
