Food grade aluminum foil bag is more and more widely used and has many characteristics, but many aluminum foil bag manufacturers have some problems in the process of customized production. The aluminum foil bag of zxpac is one of Chinese aluminum foil bag manufacturers, our products include heat seal aluminum foil bag, aluminum foil faraday bag, zip lock aluminum foil bag and aluminum foil vacuum sealer bag, etc.
Compared with the traditional standard packaging bag, there are many matters needing attention in the production of stand-up aluminum foil bag. In the production process, if the technology is not good, there will be uneven packaging bags and poor symmetry and other issues. These problems not only affect the appearance of the packaging bag, but also directly affect consumers’ desire to buy.
In fact, it is not difficult to find and solve the above problems in time, as long as we pay attention to detail control in the production process. As we all know, flatness is one of the indicators to measure the appearance quality of packaging bags. The flatness of food grade aluminum foil stand up bag is generally related to not only production material selection, but also heat sealing temperature, heat sealing pressure, heat sealing time and cooling effect.
In production, the high temperature or pressure of the thermal seal and the long time of the heat sealing will cause the shrinkage deformation of the composite film, which will affect the forming of the stand-up aluminum foil bag; Similarly, when the cooling is insufficient, it will cause insufficient shaping after heat seal and wrinkle. In addition to the problem of bottom material, the asymmetry of bag shape may also be related to photoelectric tracking, feeding, cursor design, cot balance and other factors, which need to be solved according to different packaging products and different bag making equipment in actual production.
Notice for food grade aluminum foil self-supporting bag before customization:
1. The larger the order quantity, the more favorable the unit price of the product will be;
2. The customer needs to tell us the details, such as the packing bag material, material, size, thickness, etc. to make our quotation accurately.
