Why do corrugated boxes become soft?

Why do cartons become soft. 1、 Weather factors. Wet weather in Meiyu and high environmental humidity will lead to the softening of corrugated cartons. In this way, we can solve this problem from the storage and working environment of corrugated cartons; 2、 There is a problem with the material of corrugated carton. The corrugated base paper and corrugated paperboard have poor materials, which are easy to absorb water. The corrugated carton and paperboard are naturally soft, and then the high-quality pit paper is generally replaced. Now some pit paper contains waterproof agent, which can effectively reduce or reduce the softening of some corrugated cartons.www.chinacartonmachine.com
