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.


Key Advantages of Tamper-Evident Aluminum ROPP Caps:

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.
