In the hot-pressing sealing process of the drum-type aluminum-plastic blister packaging machinery, the PVC tape and aluminum foil are hot-pressed by the roller-shaped heat-sealing rollers and anilox rollers parallel to each other under the action of a certain temperature and pressure for meshing counter-rolling. sealed. The contact between heat-sealing roller and the anilox roller is linear, and the required pressure is relatively small.

In the hot-pressing sealing process of the flat aluminum-plastic blister packaging machine, the PVC tape and the aluminum foil are made of parallel flat heat-sealing plates and reticulated plates in the same plane under the action of a certain temperature and pressure to complete the hot-pressing sealing fit. The contact between the heat sealing plate and the anilox plate is a planar contact, and the required pressure is relatively large.

Whether it is a roller type or a flat type heat-pressing sealing, when the heat-sealing mesh pattern is not clear, the mesh pattern is different in depth, and the PVC belt shifts during heat-sealing and causes blistering, etc., the following aspects need to be solved:

(1) Whether the aluminum foil is qualified product, and whether the heat sealing surface is coated with a hot sol that meets the requirements;

(2) Whether the temperature of heating device is too high or too low;

(3) Whether there is abnormal resistance in operation of PVC tape or aluminum foil;

(4) Whether the heat-sealing molds is qualified, whether the surface is flat and smooth, and whether the blister formed on PVC tape can be smoothly inserted into the hole of the heat-sealing roller (plate);

(5) Whether the texture on anilox roller (plate) is clear and consistent in depth;

(6) Whether the cooling system of heat sealing mold works normally and effectively;

(7) Whether the pressure required for the heat sealing is normal;
