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.
