Experimental Study on Moisture-Proof Coating for Corrugated Boards and Boxes

摘要

Moisture-proof coating on the surface of corrugated boards and corrugated board box is one of effective methods to satisfy a requirement of logistics distribution in damp environment. Moisture-proof coating mechanism of the corrugated board and related moisture-proof coating experimental study were discussed and carried out in this paper. Four-layer corrugated board (250 g/170 g/100 g/250 g, double C) and five-layer corrugated board (200 g/120 g/120 g/120 g/200 g, BA) were selected as experimental materials. The physical and mechanical properties of these two kinds of corrugated boards coated by damp-resistant material under different environment conditions were tested and analyzed. The optimum coating amount was determined under the conditions of temperature and humidity selected in the experiments. The results show that the combination performance of the corrugated boards and corrugated board box reached the best when the damp-resistant material consumption is 6 g/m~2 under RH65％.
