1. poor adhesion of the metal plating layer: in the production and transportation printing and other production processes, the metal plating layer falls off, resulting in the loss of thermal lamination film color patterns, and the normal composite and printing processes can not be carried out, and the effect of the finished product is poor.
2. the thickness of the metal plating layer is not uniform: if the thickness of the metal plating layer is uneven, it can be seen from the appearance that the gloss is different, the local brightness will be different when the light is observed, the thickness of the metal plating layer will be uneven, and the effect of barrier water resistance will be greatly reduced, which may lead to the problem of shortening the shelf life of the packaging products.
3. pinhole problem: the high probability of pinhole problem is caused by impurities mixed in the production of substrate film, or it may be caused by excessive control during the film stretching process. Pinhole problems are more common and require a clean production environment and skilled technical workers to greatly avoid this problem.
4. the appearance of poor color: metal plating layer can do a variety of colors, customers can customize different colors according to needs, different batches may appear color deviation, which is normal. And if the same batch of products appear with the same color but different shades, there is a quality problem, may be too long production time, improper preservation, caused by oxidation, may also be caused by insufficient purity of metal raw materials, too much impurities will make the metal plating layer yellow and dark situation.
