Take you to analyze the wrinkle phenomenon in the zipper bag

  The zipper bag is a packaging form of plastic soft plastic packaging, which is convenient for taking food and can be used repeatedly to ensure the freshness of food. From the perspective of food packaging manufacturers, the production process requirements of bags without zippers are gradually increasing. Next, our company will take you to analyze the folds that often occur in zipper bags.

  There are two common problems in zipper packaging bags: one is the local delamination or surface folds at both ends of the zipper; the other is the surface folds at the stitching of the zipper and the bag body.

  The wrinkles at both ends of the zipper packaging bag are sometimes closely related to the choice of zipper. When purchasing zippers, we must pay attention that the melting point and shrinkage rate of the zipper should be lower than or equal to the melting point and shrinkage rate of the heat sealing layer of the composite film, so as to avoid the melting point and shrinkage rate of the composite film. Wrinkling that occurs when there is a severe mismatch with shrinkage.

  The cooling condition is also one of the important factors in the bag-making process. If the deformed zipper can be sufficiently cooled before the bag-making process is completed, the composite film that has completed the bag-making process will continue to shrink under storage conditions. possibility will be greatly reduced.

  If the heat-sealing layer and zipper in the composite film bag that has been processed into the bag are still in a molten state or viscoelastic state, then, under storage conditions, the heat-sealing layer and the zipper must undergo some degree of thermal shrinkage. Then a corresponding degree of surface wrinkling occurs. Therefore, the surface temperature of the bag making machine cooling has become one of the important factors affecting the appearance quality of the composite packaging bag.
