About Food-grade Aluminium Foil Stand-up Pouches Customisation

In fact, as long as attention to detail in the production process control, timely detection and resolution of the above problems is not difficult. For example, the bag shape is not flat, as we all know, flatness is one of the indicators to measure the quality of the appearance of the bag. The flatness of food-grade aluminium foil stand-up pouches is generally related to the production of selected materials, but also with the heat sealing temperature, heat sealing pressure, heat sealing time and cooling effect and other factors. In production, too high a heat sealing temperature or too high a heat sealing pressure and too long a heat sealing time will result in shrinkage and deformation of the composite film, affecting the forming of the stand-up aluminium foil pouch later; likewise, when insufficient cooling will result in insufficient shaping after heat sealing and the production of folds.
