Corrugated box factory: Corrugated box cushioning performance is better, corrugated box cardboard has a special structure, the structure of the cardboard 60-70 volume is empty, so it also has a good shock absorption performance, is to avoid being packaged by collision and impact, firm and lightweight。

Corrugated cardboard is a hollow structure, with less material to form a rigid larger box, so light, firm, compared with the same volume of the wooden box, only 1/4 to 1/5 of the weight of the wooden box。

作用

The multi-capillary colloid characteristics of the structure determine some properties of the paper, such as absorption, permeability, hygroscopicity, deformation when water changes, and irreversible changes in properties due to drying。The structural elements of the paper have a binding force between them that determines the mechanical strength and other properties of the paper。
