Our collection of ROPP caps comes in multiple colours and sizes for businesses that bottle drinks and liquid foods.
These are aluminium bottle caps applied with suitable ROPP capping equipment, not ordinary pre-threaded screw caps.
Please browse the range and check each product page for its individual specifications.
Features and Packaging Benefits of ROPP Caps
● The aluminium design gives glass bottles a lightweight, neat closure.
● Multiple colours of available closures can help differentiate product lines and brands while maintaining a professional look.
● Some versions have ribbed upper edges that support grip and handling; confirm by checking each listing.
● Tamper-evident bands show first-opening evidence.
● Tamper-evident does not mean tamper-proof or child-resistant, and screwing a cap back on does not restore a broken band.
How to Choose Compatible ROPP Caps
Matching diameter alone does not establish compatibility. Work through this checklist:
● Diameter and height: a size written as 28×18mm usually means diameter by height, purely as an example.
● Heights vary, and 18mm is common rather than the maximum.
● Exact bottle-neck finish: the neck must suit rolled-on threads and any band.
● Liner compatibility with your contents; check each product specification.
● Capping-head tooling and settings suited to your chosen cap.
● Your intended filling and storage conditions.
● Sample testing before you commit to production.
Applications/Use Cases of ROPP Caps
Suitability depends on each closure’s specification, so confirm before ordering.
● Beverage bottling, such as water, wine or spirits, where the cap suits the bottle and contents.
● Suitable for food liquids, such as oils, subject to the liner and closure specification.
● Carbonation, hot filling, pasteurisation and sterilisation are not assumed; confirm each separately.

Frequently Asked Questions
What does ROPP mean?
ROPP means Roll-On Pilfer-Proof. Rollers form the aluminium cap’s thread around a compatible threaded bottle neck during application.
Can I apply ROPP caps by hand?
No. Initial application needs suitable ROPP capping equipment, which forms the thread and any tamper-evident band. It is not the same as hand-tightening an ordinary pre-threaded screw cap.
Are all ROPP caps 18mm high?
No. 18mm is a common height, but not the maximum across the ROPP market. Check each product page for exact dimensions.
Will a ROPP cap fit any screw-neck bottle?
No. Diameter, height, neck finish, liner, and machine tooling must all be compatible. Matching one measurement is not enough.
