This blister packaging system comprises a rotary-style blister machine, a reciprocating sealing pillow packaging machine, a cartoning machine with high-speed capabilities, and an overwrapper.
The blister machine’s punching station comes with a servo manipulator that takes the blister cards and places them onto the conveyor belt, which then leads to the pillow packaging machine. This machine has a reciprocating heat-sealing structure that allows the heat-sealing plate to move in sync with the packaging materials for an extended period of time. Compared to the traditional drum heat-sealing method, this reciprocating heat sealing provides better heat sealing and barrier properties as it prolongs the heat sealing time.
The trend of using a combination of blister and pillow packaging is on the rise. This is because thermoformed PVC has poor barrier properties that make it unsuitable for certain drugs that require high moisture resistance. Although the cold-formed aluminum film has better barrier properties, its feeding system is complicated, and production efficiency is low. Consequently, many pharmaceutical companies opt for pillow packaging after blister packaging. This cost-effective method provides good packaging barrier properties, making it increasingly popular.
Once the pillow pack is complete, a disc manipulator under servo control takes hold of the item and quickly transfers it to the cartoning machine. This machine operates at high speed, continuously pushing the material into the carton using a set of push rods. Additionally, a rotary suction carton device fitted with several suction cups continuously picks up cartons, opens them, and places them onto the conveyor chain.
When the cartoning process is complete, the carton undergoes overwrapping. Firstly, the cartons are rotated 90 degrees and grouped together. These groups are then pushed into overwrapping packaging, which uses a gentle film to cover the packaging from all angles. Any surplus film is overlapped and sealed on both sides. This enhances the package’s airtightness and makes it easier to transport.
