And its waterproof performance is a highlight of the hollow board.

The waterproof performance of hollow core plastic sheets is mainly due to its special production process andmaterial selection. Coroplast sheets use high-quality polypropylene as the main raw material, which has good waterproof properties and weather resistance. At the same time, the cavity structure of corflute sheets also plays a very good waterproof role, which can effectively prevent moisture from entering.

In addition, the surface treatment of pp corrugated board is also an important guarantee for its waterproof performance.  By carrying out special treatment on the surface of pp hollow sheets, such as coating with waterproof coating or applying waterproof membrane, its waterproof performance can be further improved, so that it can maintain good use results in various harsh environments.

In short, the waterproof performance of corflute is one of the important reasons for its wide application.
