Customized 28mm ROPP Aluminum Bottle Cap - Non-Fillable, Suitable for Glass Bottles

The 28mm ROPP aluminum bottle cap is a roll-on pilfer-proof (ROPP) cap with a 28mm diameter. It is widely used in industries such as food, beverages, pharmaceuticals, and alcoholic beverages—especially for glass packaging of products like wine, liquor, edible oils, and health supplements.

ROPP (Roll-On Pilfer-Proof) caps are aluminum screw caps applied by mechanical roll-on techniques to secure the cap onto glass bottles. Made from high-quality aluminum alloy, these caps offer a lightweight, high-strength, and corrosion-resistant solution to ensure product sealing and shelf stability.
 

1.Tamper-Evident Design: The tamper-evident band remains attached to the cap after opening, providing clear evidence of tampering and preventing refilling.
2.Non-Fillable: The tamper-proof structure ensures the bottle is single-use and cannot be resealed once opened, complying with safety packaging standards.
3.Material & Performance: Constructed with aluminum shell and non-PVC liners, offering rust resistance, recyclability, and a stable sealing barrier.
4.Corrosion Resistance: Food and pharmaceutical grade corrosion resistance—non-reactive with the contents.
5.User-Friendly: Easy for consumers to open and reseal, ideal for frequent-use applications.
