Automatic Ropp Screw Capping Machine

The machine is available in different models:

• Single Head: Up to 40–60 bottles per minute
• Four Head: Up to 80–120 bottles per minute
• Six / Eight Head: Up to 150–200 bottles per minute (depending on model)

Output varies based on bottle size, cap diameter, and product characteristics.

The Automatic ROPP Screw Capping Machine supports a wide range of formats:

• Bottle Diameter: 24 mm to 90 mm
• Bottle Height: 50 mm to 250 mm
• ROPP Cap Sizes: 20 mm, 25 mm, and 28 mm (with suitable change parts)

It is suitable for both glass and plastic bottles commonly used for syrups, oral liquids, and pharmaceutical products.

ROPP (Roll-On Pilfer Proof) capping uses aluminum caps that are rolled and crimped onto the bottle neck, providing a strong tamper-evident seal. Once opened, the pilfer-proof ring breaks, clearly indicating tampering. In contrast, normal screw capping simply tightens plastic or metal threaded caps. ROPP capping is preferred in pharmaceutical and liquor industries where product integrity and security are critical.

The machine comes with multiple safety interlocks for reliable operation:

• No Bottle – No Cap system
• No Cap in Chute – Machine Stop (via sensors)
• Safety clutch mechanism to prevent bottle breakage during jamming
• Overload protection
• Precise torque and rolling pressure control for consistent sealing

These features ensure minimum product wastage and high operational safety.
