AI Technical Summary

Technical Problem

Existing corrugated cardboard has poor waterproof performance. When it comes into contact with water, the bonding strength decreases, causing the corrugated cardboard box to absorb water and soften, the edges to peel off and curl, deform, and it is also weak in load-bearing capacity and easy to break.

Method used

By employing a reinforcing layer, silicone layer, and supporting structure design, combined with a hydrophobic and oleophobic coating, and utilizing the high tensile strength of the fiber filaments and the principle of triangular stability, the physical properties and load-bearing capacity of corrugated cardboard are enhanced.

Benefits of technology

It improves the bursting strength, tear resistance, and water and oil resistance of corrugated cardboard, enhances its load-bearing capacity, and prevents it from collapsing under pressure.
