Spiral YO book printing refers to the folding carton and color corrugated box made of plastic, cardboard and corrugated cardboard. It has the characteristics of light weight, portability, wide source of raw materials, environmental protection and exquisite printing. Some good products will choose Spiral YO book printing. This requires them to do better in terms of beauty and practicality, but in fact, they often encounter some packaging boxes that are soft or damaged corners, which not only does not play a role in packaging from the box itself, not to mention aesthetic issues, so how do we ensure its hardness is very important.
The corrugated paper used in general packaging is more absorbent than other packaging. If the box is in a relatively humid environment for a long time, the water content of Spiral YO book printing paper will rise and the strength will decrease. When the relative humidity is 85%, the compression strength of the ring will decrease by about 60%. If the color box needs to be in a humid environment for a long time, it is recommended that Spiral YO book printing paper should be used with better moisture resistance.
Sometimes we don't know the moisture-proof effect of paper, so we need to test Spiral YO book printing to confirm the moisture-proof effect of paper. Now, in order to improve the waterproof performance of the surface of base paper, Many paper mills will add certain additives in the papermaking process to improve the waterproof performance of Spiral YO book printing paper, however, because the price of such additives is relatively high, the price is also relatively high.
