Thermal-sealing problem of aluminum blister packing machine

Thermal-sealing problem of aluminum blister packing machine

Whether it is drum type or plate type hot sealing, when the heat sealing mesh is not clear, the depth of mesh is different, the P, V and C belt running during thermal sealing caused by broken bubbles and other problems need to be solved from the following aspects:

(1) Whether the aluminum foil is a qualified product, and whether the thermal bonding surface is coated with the required thermal sol;

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

(3) whether there is abnormal resistance in the operation of P, V and C belts or aluminum foil;

(4) Whether the heat sealing mold is qualified, whether the surface is smooth and smooth, and whether the bubble cap formed by PV C belt can be smoothly set into the holes of the heat sealing roller (plate);

(5) the anilox roller (plate) on the anilox is clear grain, consistent depth;

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

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

(8) whether the heat sealing roller (plate) and anilox roller (plate) are parallel.
