## Overview

This ROPP cap is an aluminum shell rolled onto the bottle thread during capping. The rolled band breaks on first opening, giving clear tamper evidence. A TPE liner seals against the bottle lip to prevent leaks, and the ribbed skirt gives a firm grip. ROPP caps need a capping head that rolls the thread, so they are typical for automated spirits lines.

The cap is listed as a 28 mm closure for vodka, whisky and other liquor bottles; the specs also show an 18 mm inside diameter, so confirm the size against your bottle neck. Logos can be applied by silk screen or UV printing, as requested. The listed maximum continuous temperature is 150 °F. The minimum order is 10,000 pcs.
