Description

Waterproof corrugated board and corrugated board production line are with neat device Technical Field The utility model belongs to the field of corrugated boards, and particularly relates to a waterproof corrugated board and a trimming device for a corrugated board production line. Background Corrugated board is a common packaging material, which is mainly formed by bonding surface paper, core paper and lining paper through adhesives, and the corrugated shape in the structure of the corrugated board endows the board with good compression resistance and buffering performance. However, the conventional corrugated board has a remarkable disadvantage in terms of waterproof performance, and particularly, is easily deformed by water absorption in a humid environment, resulting in a decrease in strength and stability of the packaging material, thereby affecting the protection of the contents. With the rapid development of logistics and packaging industries, the market has put higher demands on the performance of corrugated boards. Particularly, in some humidity-sensitive commodity packages, such as foods, medicines, electronic products and the like, the common corrugated board is difficult to meet the requirements of water resistance and moisture resistance.
