Usually the face paper of the pre-printed corrugated carton is whiteboard paper, which is the outermost layer of the corrugated carton when it is mounted, so it is also the easiest to contact with the outside air moisture. Therefore, some technical indicators of whiteboard also directly affect the moisture resistance of the entire carton.
According to the experience of the production process, the printing surface roughness, smoothness, glossiness and water absorption of whiteboard paper have a great influence on the moisture resistance of the carton. Therefore, when ordering, it must be emphasized that these technical indicators should be controlled within the scope of national standards, or even requirements It can also be higher than the national standard to improve the moisture resistance of the carton. Especially for post-press processing of whiteboard paper with a glazing process, the poor quality of the paper surface is easy to absorb oil, so that the paper surface lacks the proper oil layer and brightness, and it is easy to absorb external moisture.

In the production process practice, it is found that the white paper with high quality grade has a higher brightness on the paper surface after glazing. On the contrary, it obviously lacks the brightness and its moisture resistance is also poor. Therefore, according to the difference in food quality grade and the temperature and humidity of the place of sale, choose the appropriate grade of whiteboard paper for printing, which can not only take into account the economics of moderate packaging, but also better achieve moisture-proof packaging and meet the quality requirements of market use. .
