Research on Secondary Fiber Elastic Repair for High-Strength Packaging Materials

摘要

To research the method of improving the secondary fiber strength for high-strength packaging paper products, on the basis of analyzing the secondary fiber species and performance, we emphatically analyzed the principle and repair effect of mechanical method and enzymatic method. Probing the effect of repair technology of secondary fiber combined with the two methods has environmental characteristics. The results demonstrate that mechanical treatment and enzyme treatment method can make the secondary fiber main packaging performance increased by more than 20 % including ring crush strength and breaking length. Combining the two methods will be more to restore the strength of the secondary fiber performance.
