High-speed blister packaging machines are classified into two types based on their level of automation: semi-automatic packaging machines, automatic packaging machines, and fully automatic production lines. Pharmaceutical packaging (tablets, capsules, suppositories, etc.) primarily utilizes automatic packaging production lines, also known as PTP (Press Through Pack) automatic packaging lines. These lines are available in horizontal and vertical configurations, generally employing a multi-row structure, offering high productivity and good packaging quality. They are equipped with detection devices and waste rejection mechanisms, and can integrate printing, distributing instruction manuals, and boxing processes into the production line. This is a comprehensive and typical automated packaging production line.
High-speed blister packaging machines produce blister packs, cavities, and trays of varying sizes and shapes, depending on the shape of the packaged item. Some use linings, while others do not; moreover, there are many types of blister packaging machines and various blister packaging methods. Nevertheless, the basic principles of blister packaging remain largely the same, with a typical process as follows:
Plastic sheet heating → Film forming → Product filling → Substrate covering → Heat sealing → Edge trimming
This process can be completed using manual, semi-automatic, and automatic operation.
Because pharmaceutical blister packaging involves large production batches, relatively fixed product types, and requires safety and hygiene, automated blister packaging lines are recommended. In automated operation, in addition to packaging, processes such as printing, instruction manual filling, and boxing can be integrated with the packaging line to form a fully automated blister packaging production line.
