Also known as flat-type aluminum-plastic blister machine, the flat blister packaging machine is multi-station automatic packaging equipment widely adopted for solid-dose product packaging in the pharmaceutical industry. It produces unit-dose blister packs featuring lightweight structure, easy portability, reliable sealing performance, zero cross-contamination between products and minimal material waste. For these benefits, flat blister packs have become the mainstream packaging solution for pharmaceutical solid preparations across China and global pharmaceutical manufacturers.

Different from roller-style blister machines that use continuous roller forming, flat blister packaging equipment completes every packaging procedure at independent intermittent stations. Multiple film-transport mechanisms drive plastic packaging film sequentially through forming, filling, heat-sealing, coding and punching stations to finish full blister production cycles.

The machine supports multiple traction drive solutions for film conveyance. Available mechanisms include Geneva wheel mechanism, cam rocker mechanism, cam indexing mechanism and ratchet mechanism.

Users can select the proper mechanism according to core requirements:

• Positioning accuracy of film feeding
• Acceleration curve for intermittent movement
• Physical adaptability of packaging raw materials (PVC, PET, PP aluminium foil)

Heating & Thermoforming Principle

The full workflow is divided into 4 sequential core steps:

1. Blister forming: Plastic packaging film passes through the heating unit and becomes softened. Compressed air inside the flat forming mould blows softened film into custom blister cavities. Operators can swap forming dies to achieve various blister shapes and depths for different products.
2. Material filling: A matched filling unit dispenses products into pre-formed blister pockets. Filling devices are interchangeable to adapt for tablets, hard capsules, soft capsules, medical hardware or small special-shape components.
3. Heat sealing & coding: The blister web moves to the sealing station. Under calibrated temperature and pressure, cover aluminium foil bonds tightly with plastic blister bases. Afterwards, typing and embossing assemblies print production batch numbers, expiry dates, and press tear-off / easy-break lines on sealed packs.
4. Punching: Finished continuous blister strips go through the punching station, where they are die-cut into finished blister plates of specified dimensions. Trim waste material is discharged separately.
