The disadvantages of kraft paper bags:
The main disadvantage of kraft paper bags is that they cannot encounter water. The kraft paper that encounters water is softened, and the entire kraft paper bag is softened by water.
Therefore, the place where the bag is stored must be kept ventilated and dry, and plastic bags do not have this problem. .Another small disadvantage is that if the kraft paper bag is to be printed with rich and delicate patterns, it will not achieve that effect. Because the surface of the kraft paper is relatively rough, there will be uneven ink when the ink is printed on the surface of the kraft paper. Therefore, compared with plastic packaging bags, the printing patterns of plastic packaging bags are relatively delicate. Hongming Packaging believes that if the items packaged in the packaging bag are liquid, the packaging material should not be made of kraft paper. Of course, if must use kraft paper suggest to use the lamination that avoid the liquid touch to the paper directly.
