System Description, Operating Principle, Technical Specifications, and Application Areas
Specialized cap closure systems are designed for functional or security-focused caps that differ from standard screw or snap-on systems.
The main cover types included in this group are:
- ROPP (Roll-On Pilfer-Proof)Aluminum caps are screwed onto the bottle neck and then screwed on.
- Pump / Spray Nozzles: Requires height and shape-sensitive application.
- Vacuum-Assisted ClosureEspecially with food products, the lid is sealed under vacuum.
These systems are specifically configured according to the product shape, lid function, and industry requirements. They are critical for product safety, leak-proofness, and shelf life.
Operating Principle and Packaging Compatibility
Each subsystem operates on a different principle:
- ROPPThe aluminum cap is first placed, then shaped onto the bottle neck using a rotary crimping head.
- Pump/SprayThe cap is sealed onto the bottle using a special pressure or torque-controlled cap after it has been placed on the bottle.
- Vacuum SystemThe bottle is sealed in a vacuum chamber; then it is brought to atmospheric pressure.
Cover Type | Eligibility Status |
ROPP (Aluminum Cap) | ✅ Most suitable |
Pump Nozzle (Knee/Spray) | ✅ Suitable |
Trigger / Flip-top / Lotion | ✅ Suitable |
Plastic Screw/Snap-on Cap | ⚠️ Suitable, but these systems are not necessary. |
Private Security / Sealed Lids | ✅ Suitable |
📌 Note: These systems typically operate with low tolerances and require high precision.
