　　The edge of the aluminum foil bag is high, the hot knife is high, the edge is wrinkled, and the temperature is low and it cannot be sealed. The pressure is debugged, the silicone pads and raw materials have been changed, or it can't be solved. What is the way?

　　2. It is not temperature -resistant enough for materials, and the ingredients are wrinkled after the corn bag is sealed at high temperature;

　　3. It is not temperature -resistant enough glue and ink; 4, the parallelism of the hot knife of the bag making machine, the softness and flatness of the silicone are not met with the heat sealing requirements, and there are foreign bodies on the hot seal knife.

　　The reason for the problem that cannot be sealed is usually:
