Causes and solutions of wrinkles on the packaging film of the four-sided sealing granule packaging machine 1. Reasons for wrinkles on the film (1) The heat sealing temperature is too high, the film is heated too much, and the upper film shrinks; The heat-sealing plate stays for a long time, the film is subjected to a lot of heat, and the film shrinks; (3) There are wrinkles on the film before heat-sealing; (4) There are foreign objects on the heat-sealing plate or scratches on the heat-sealing plate; (5) Heat seal gaskets are uneven. 2. The solution for sealing the crease of the granule packaging machine on all sides (1) Reduce the heat sealing temperature, reduce the heat of the upper film, and reduce the shrinkage of the upper film; (2) To ensure that the film is always running and produced, and reduce the number of starts and stops, In order to reduce the problem of overheating of the upper film during shutdown, and avoid wrinkles caused by shrinkage and deformation of the film. The upper film when heated; (3) There are wrinkles on the film before heat sealing.
If film is used, the product quality should be controlled during production to avoid wrinkles. If the film is under the film, wrinkles will appear before stretching, and the quality of the product should be controlled during the production process. Avoid wrinkles; if there are wrinkles in the process of stretching the lower film, it indicates that the lower film is heated too much during the stretching process, which reduces the stretching temperature, stretching preheating time and stretching forming time; or the lower film is heated during stretching There is a foreign object on the board or the board is damaged.
Remove foreign objects and trim the heating plate; (4) Remove foreign objects on the heat sealing plate and trim the heat sealing plate; (5) Trim the heat sealing gasket to ensure that the heat sealing gasket is flat and has no gaps.
