The most commonly used face paper for packaging box printing is coated paper, and a film on the surface of coated paper is the best choice for box face paper. It can not only print color on it, but also add a lot of special processes, as well as waterproof and dirty functions. But there are good and bad coated paper, the toughness is not good coated paper in the box when it is easy to break off powder. Some coated paper is not pure enough, there are impurities, impurities reflected on the surface will be black spots and so on, affecting the overall effect of packaging box printing.
There is special paper, general special paper can not be coated, some special paper with deep grain or color is not suitable for printing, the biggest impact on the packaging box printing is the wear resistance, some paper toughness is not enough coupled with no film, it is easy to break. Because the surface can not be printed, so requires the paper itself to have a certain color and gloss.
Covered with film paper can be reworked to wipe glue, but not covered with special paper is not. Once there are dirty points or glue is equal to the box scrapped, which is undoubtedly more difficult for the production of packaging boxes, so if it is difficult to do the box to choose coated paper, simple boxes can choose special paper. In the packaging box printing selection paper must not be used in order to save costs and poor paper, but finally more than worth the loss.
