30 x 35 EPE tin liner ROPP Closures Structure

Dimensions: Precisely 30 mm in diameter and 35 mm in height, designed to fit standard spirit/wine bottle necks (e.g., GPI-1660 or R3 finish).
Material: High-grade aluminum alloy (e.g., 8011 series), offering excellent ductility for thread forming, corrosion resistance, lightweight, and recyclability.
ROPP Mechanism: Roll-On Pilfer Proof technology; the aluminum shell is pressed onto the bottle neck using a capping machine that forms the threads and tamper-evident band. Once opened, the tamper-evident band breaks, leaving visible signs of tampering.
Liner: Composed of EPE (Expanded Polyethylene) foam laminated with a polyethylene film.

Advantages of ROPP Closures with EPE Liner

Chemical Resistance: Suitable for high-proof spirits (>50% ABV), acids, oils, and solvents.
Sealing Performance: Compressible foam conforms tightly to the bottle neck, creating a leak-proof barrier.
