28mm Brushed Aluminum ROPP Cap with EPE Liner

HAOMEI Aluminum produces 28mm brushed aluminum ROPP capsas a sealing solution for 28mm aluminum bottles. With a brushed aluminum finish, this closure creates a unified mono-material package, widely used in the spirits and beverage markets.

This cap is equipped with an EPE liner to ensure secure sealing and leak-proof performance, maintaining product freshness and integrity. Its roll-on pilfer-proof (ROPP) tamper-evident design enhances product safety and consumer confidence.

Brushed Aluminum Finish - ROPP Cap

The ROPP aluminum closure is manufactured from brushed aluminum material. The brushing process gives the cap a refined texture, forming delicate and even lines on the surface through mechanical friction. This not only enhances the premium appearance of the cap but also reduces fingerprint marks, keeping it clean and elegant over time.

Available in silver, gold, or customized brushed colors, the cap showcases the natural shine and texture of metal, adding a luxurious touch to packaging. This makes it especially suitable for premium cosmetics and nutraceutical brands.

Aluminum itself has excellent anti-oxidation properties, and after brushing, the dense oxide layer on the surface further strengthens corrosion resistance, preventing deformation, rust, or material aging.

EPE Liner

EPE (Expanded Polyethylene), also known as pearl cotton, is widely used as a cap liner due to its outstanding cushioning and sealing properties. It can be produced in different colors; for example, pink EPE with antistatic agents provides significant antistatic performance.

Advantages of EPE Liner in ROPP Caps:

• Excellent cushioning: Proven through vibration and drop tests to protect contents effectively.

• Superior sealing: Ensures airtight packaging, preventing leakage or gas exchange.

• Chemical stability: Corrosion-resistant and non-reactive with contents, keeping products pure.

• Eco-friendly: Free of heavy metals, non-toxic, odorless, and compliant with food-contact safety standards.
