Aluminum foil bag sealing side, the high temperature hot knives, sealing side is corrugate, low temperature and sealing. Pressure debugging, silicone mat leather and raw materials are changed, is still not solve, could you tell me what method? A: from two aspects to consider, a sealing side is corrugate, 2 it is not sealed. Wrinkle for sealing side, the reason: 1, is the residue of glue and ink solvent is overmuch, agglomeration in the process of hot sealing evaporation which appear the phenomenon such as bubble wrinkles; 2, heat sealing bag making machine knife parallelism, silica gel hardness, flatness did not meet the requirements of heat sealing, heat sealing knife on a foreign body, etc. 3, data is not heat resistance, wrinkle after high temperature hot sealing materials; 4, is no noe of glue and ink; To the problem of sealing of reason is: 1, heat sealing temperature is too low and the pressure is too small. 2, the quality problem of the heat sealing material, sealing temperature is too high, perhaps unstable heat sealing function. 【 Vacuum bags 】 【 Plastic bags 】
