Forming process of PTP blister cover foil

Thermoformed blister foil

Thermoforming blister molding is the process of unrolling the plastic film or sheet from a reel and guiding it through a preheating station on the blister production line. The temperature softens the plastic and makes it flexible. The warm plastic then arrives at the molding station and is extruded to form the bubble chamber into a negative mold. After the mold cools, the plastic hardens again and retains its shape when removed from the mold.

Cold formed blister cover foil

The cold forming PTP bubble cover is formed by simply pressing the aluminum base film into the mold by pressing the mold. Aluminum is stretched to retain its tensile shape. The industry is called cold formed bubble cover.

Hot and cold forming blister cover foil

Hot and cold molding is the use of two ways, first through the hot molding technology to complete the first packaging, and then use cold molding packaging to complete the second step.
