1. The adhesive is hardened by heat preservation aging, which can increase the strength and heat resistance of the composite film of the hot sealing and cold cutting bag making machine.
2. When selecting the heat sealing conditions, choose according to the structure of the composite film, the heat sealing state and other conditions, or improve the heat sealing mode, and cool down in time after heat sealing.
3. Regularly check the shelf life and preservation conditions of the heat sealing film, and pay attention to the old batch number or the heat sealing film.
4, enhance the thickness of the heat seal film.
5, change the type of heat sealing film, choose the inner sealing film with anti-pollution heat sealing.
6, improve the thermal sealing performance of the heat sealing layer.
7. After heat sealing, detect the processing degree of the heat cover and adjust the appropriate heat sealing temperature.
