Zipper bags often show unevenness, delamination, dead folds, powder, difficult to open teeth, opacity, etc., which have become a setback in the quality management of zipper bags and severely affect the effect of packaging products. In response to these problems, the professional flexible packaging manufacturer Better Packaging combined with its own production experience to provide solutions, hoping to help Fanbo customers to avoid poor products and order high-quality zipper bags. 1. Common problems The sealing part of the zipper and the bag body is not flat; the part where the zipper is sealed with the bag body has partial delamination; the part where the two ends of the zipper intersect with the side seal of the bag has "dead folds"; The part where the two ends of the zipper intersect the side seal of the bag has partial delamination; the easy-opening zipper bag has powder; the powder-free zipper bag is difficult to open; the transparency of the zipper bag is not good. Second, the solution: Through the professional flexible packaging manufacturer Better Packaging, comparative observation and testing of various types of zipper bags with undesirable phenomena, the above problems should be solved as follows: the heat shrinkage rate of the zipper itself is greater than that of the composite film; the zipper itself The melting point is greater than or equal to the melting point of the heat-sealing film; the cross-section of the snap button on the zipper is too large; the local heat-sealing rod on the zipper bag making machine is unfairly designed. It is recommended to use an ultrasonic heat-sealing device; the local heat-sealing head design Unfair (too small); insufficient output power or insufficient pressure of the ultrasonic heat sealing device; insufficient heat resistance of the ink layer; Better packaging through adjustment of the raw material formula and fair optimization of the production process, successfully made the PE garment bag have high transparency and no powder , Yiqiqi and other industries have advantages. In addition, the PE garment bags produced by Better Packaging look chaste without any impurities, no wrinkles, no stains, and the surface feels smooth, delicate and super tough. In addition, the garment bag craftsmanship of Better Packaging is more improved, the quality can be finely controlled, and the production can be satisfied and efficient.
