See other people's boxes do not show glue marks do not show fluting, box compressive strength good hard, but the surface of their own boxes a strip of corrugated lines, but also floppy no point hardness, you follow the method I said with glue, to ensure that you do not only look good boxes can also be load-bearing!
This is indeed closely related to the glue, so a good paper laminating glue will definitely allow you to get twice the result with half the effort!
Below we analyze in detail, and teach you how to solve the problem:
1, first of all, if the box index requirements are high, it is highly recommended to use high purity low water ratio of high viscosity quick-drying glue
2, also according to the season or different customer needs to add appropriate glue enhancer
3, the amount of glue on the glue does not affect the bonding situation, the smaller the amount of glue the better
4, the glue solid content of low moisture is too large, the pressure caused by the glue line is too wide and too heavy through the paper
5, the face paper paper is too poor or grams too low, strong water absorption, will also cause the obvious flute, cardboard moisture back to soft
6. Don't hit the water stick when laminating the glue.
7, the face paper and corrugated board grain is cross-shaped laminating glue
8, framed cardboard if possible to use ventilation or emission equipment to shoot out the cardboard moisture, reduce the shrinkage of the face paper and corrugated cardboard after laminating (cardboard flute wrinkle are applicable).
