Whether you are a pharmaceutical company, food producer, or electronics manufacturer, choosing the right blister packaging machine is crucial for product quality, production efficiency, and cost control. This article will guide you through the essential selection criteria, technical specifications, and purchasing considerations.
1. Working Principle and Basic Classification of Blister Packaging Machines
Working Principle
The fundamental working principle of a blister packaging machine involves heating a thermoplastic film (such as PVC or PET) until it softens, then forming it into blisters using either vacuum suction or compressed air. Products are then filled into these formed cavities, and finally, a lidding material (aluminum foil, paperboard, etc.) is heat-sealed to the film to complete the package.
This thermoforming process utilizes the vacuum created by a pump or positive pressure from compressed air to shape the softened plastic sheet over or into a mold, creating various shapes of blisters, trays, or clamshells.
Main Types
Based on structure and forming method, blister packaging machines are generally categorized into three main types:
| Type | Working Principle | Features | Suitable Applications |
|---|---|---|---|
| Rotary (Roll) Blister Packaging Machine | Vacuum forming using negative pressure; rotary drum heat sealing | Continuous operation, high efficiency, ideal for large-scale production | Pharmaceuticals, capsules, standard-shaped products |
| Flat-Plate (Platen) Blister Packaging Machine | Compressed air forming using positive pressure; flat-plate heat sealing | Excellent forming quality, easy mold change | Irregularly shaped products, small batches with high variety |
| Roll-Plate (Combination) Blister Packaging Machine | Flat-plate positive pressure forming; rotary drum sealing | Combines advantages of both, high speed and stability | High-speed automated production lines |
Furthermore, based on the forming technology, they can be classified into Thermoforming and Cold Forming. Thermoforming is suitable for plastic films, while Cold Forming (e.g., Alu-Alu blisters) is used for products requiring extremely high barrier protection. It forms the cavity by mechanically pressing aluminum foil at room temperature.
