Parameter

Application

Roll-on Pilfer-Proof (ROPP) caps are gaining popularity in the beverage and food sectors due to their broad range of applications. They are extensively used in industries including liquor, pharmaceuticals, beverages, food processing, agrochemicals, edible oils, lubricants, and more.

A major benefit of ROPP caps lies in the flexibility of their capping heads, which can be quickly adjusted to fit bottles of different shapes and sizes.

These capping heads feature two threading rollers and two sealing rollers, enabling them to handle caps of varying diameters and heights—whether standard semi-deep drawn, deep drawn, or extra deep drawn designs. This versatility ensures smooth adaptation to diverse container types, delivering reliable and efficient sealing across a wide spectrum of products.

FAQ:

Q1: Why is the bottle cap loose or not sealed tightly after capping?

Possible causes:

• Capping head height improperly adjusted (too high or too low)

• Bottle cap size doesn’t match the bottle thread

• Insufficient capping pressure

• Bottle mouth deformed or dirty

Solution:
Recalibrate the capping head height, verify cap and bottle compatibility, increase capping pressure (test sealing after adjustment), and clean the bottle mouth.

Q2: Why does the cap get stuck or flip during the cap conveying process?

Common causes:

• Cap rail width set too wide or too narrow

• Incorrect vibration frequency of the cap bucket feeder

• Excessive caps stacked causing friction

How to fix:
Adjust the cap rail width to fit the cap diameter, optimize vibration frequency of the feeder plate, and reduce the number of caps fed at once.

Q3: Why are bottles broken or crushed during capping?

Main causes:

• Excessive capping pressure

• Misaligned bottle position with capping head

• Defects in bottle material

Solution:
Lower the capping pressure, check and correct conveyor positioning, and inspect bottle quality samples.
