Differences Between Roller Blister Packaging Machines and Flat-Type Blister Packaging Machines

Differences Between Roller Blister Packaging Machines and Flat-Type Blister Packaging Machines

Roll-through blister packaging machines (Roll-Through Blister Packaging Machine) and flat-type blister packaging machines (Flat-Type Blister Packaging Machine) are two common types of blister packaging equipment. They differ in forming methods, production efficiency, material compatibility, and applications.

1. Different Forming Methods
Comparison Roll-Through Blister Machine Flat-Type Blister Machine
Forming Method Continuous rolling (rotary die) Flat-die pressing
Forming Pressure Lower, suitable for thinner films Higher, suitable for thicker/deeper blisters
Blister Uniformity Shallower blisters, slightly less consistent Adjustable depth, more precise forming
Roll-Through: Plastic sheets are heated and formed by rotating roller dies, suitable for shallow blisters (e.g., tablets, small pellets).
Flat-Type: Plastic sheets are pressed in flat dies, suitable for deep or irregular blisters (e.g., large capsules, electronic components).

2. Different Production Efficiency
Comparison Roll-Through Flat-Type
Production Speed High (100-400 cycles/min) Medium (30-120 cycles/min)
Batch Suitability Large-scale continuous production Small/medium batches, multi-variety
Mold Change Time Longer (requires roller adjustment) Shorter (flat dies are easier to replace)
Roll-Through: Continuous rolling for high efficiency, ideal for standardized products (e.g., pharmaceutical tablets).
Flat-Type: Intermittent pressing, slower but more flexible, suitable for customized packaging.

3. Different Material Compatibility
Comparison Roll-Through Flat-Type
Sheet Thickness Thinner (0.2-0.5mm) Thicker (0.3-0.8mm)
Blister Depth Shallower (usually <15mm) Deeper (up to 30mm+)
Lid Material Aluminum foil, composite films Aluminum foil, composite films, rigid lids
Roll-Through: Best for softer materials like PVC/PET, shallow blisters.
Flat-Type: Suitable for rigid materials like PP/PVC, capable of deep or irregular blisters.

4. Different Applications
Comparison Roll-Through Flat-Type
Pharmaceuticals Tablets, capsules (standard shapes) Large capsules, medical devices
Food Industry Candies, small snacks Chocolate, bulky foods
Electronics Small components Precision parts, large products
Roll-Through: Ideal for standardized, high-volume production (e.g., OTC drugs).
Flat-Type: Better for customized, high-precision packaging (e.g., medical devices, premium electronics).

Conclusion: How to Choose?
Choose Roll-Through: High speed, mass production, shallow blisters, standardized products (e.g., pills).

Choose Flat-Type: High precision, deep blisters, irregular shapes, small/medium batches (e.g., medical equipment).

Both have advantages; the choice depends on product requirements and production needs.
