纸的固有特性导致瓦楞纸板的强度较低、耐撕裂性能不好,特别是在潮湿的环境中,其制品往往已无法达到包装保护的要求,当所装物品重量大于瓦楞纸板的承受力时,其摇盖处、提手处、负重处也常常容易炸裂,为此,人们一直在探索增强瓦楞纸板强度的方式,目前普遍的增强方式为:增加瓦楞纸板层数,采用高强度的原纸等。
The inherent properties of paper led to corrugated cardboard lower strength, tear resistance is not good, especially in humid environments, the products often can not meet the requirements of packaging protection, when the weight of the loaded items is greater than the tolerance of corrugated cardboard, For example, the way of increasing the strength of corrugated cardboard has been explored for its shaking cover, handle, and load-bearing place. For this reason, the commonly-used reinforcing methods are as follows: increasing the number of layers of corrugated board and adopting high-strength base paper.
