Videojet printing solutions for blister packaging

Blister packaging is comprised of PET (polyethylene terephtalate) or PVC (polyvinyl chloride) plastic packaging. The rugged material used for blister packs makes them ideal for a wide range of applications, such as pharmaceuticals, electronic equipment, or toy products. Blister packs eliminate the need for additional cartons, thereby reducing the cost of packaging.

Blister packs are sight packs (or retail packs). The blister pack machine closes the package inside which the blister is joined to the lining material normally by heat sealing. Lastly, the pack is closed by activating the heat seal layer (the blister cover), sealing the seams with pressure and heat.

Blister machines can be designed for hot and cold forming processes, for the processing of conventional films such as PVC, PVDC, Alu/ Alu, Aclar and PP.

Case Study

Medreich PLC Case Study




Medreich PLC, UK, predominantly specializes in thermoform blister packing of over-the-counter (OTC) and prescription drugs used for pain relief and other physical and mental health conditions. Coding and marking requirements on Medreich PLC blister pack applications have changed,since some European customers are already moving towards single dose marking of each blister pack pocket. This increasingly popular practice creates a challenge in that all of the individual pockets must be marked with a batch and expiration within the cycle time of the packaging line.

Marking across the blister web to print multiple codes in a single pass can be achieved with Wolke TIJ printers, as they have the ability to print with four heads simultaneously. In addition, the Wolke m600 TIJ printers offer a range of features that make it especially suitable for Track and Trace applications. Learn more....
