To meet the growing demands for anti-counterfeiting, tamper-resistance, and brand identity, HAOMEI Aluminum introduces a non-refillable aluminum-plastic composite bottle cap, aiming at the high-end market segment. The new 33x47mm cap is manufactured using fully automated lines for stamping, injection molding, assembly, and inspection, ensuring high consistency and efficiency. The company is certified with ISO 9001, ISO 45001, and other quality and safety standards, ensuring a reliable user experience.
This high-performance composite cap is widely used in the packaging of white spirits, health supplements, medicinal liquors, and other premium beverages.
Structure and Design of Non-Refillable Cap
Dual-Material Composite
The cap is made from an aluminum alloy shell combined with a food-grade plastic liner (typically PE or PP). The outer shell is processed through anodizing, spraying, hot stamping, etc., offering a refined appearance and excellent corrosion resistance. The precisely designed inner liner ensures long-term sealing and leak prevention.
Non-Refillable Design
The aluminum-plastic structure includes tamper-evident features. The outer aluminum prevents re-opening, while the inner plastic ensures tight sealing. This design is ideal for products that require strict tamper protection, such as white spirits, medicinal liquors, and functional beverages.

Key Technical Features of the 33x47mm Tamper-Proof Cap
1.Non-Refillable Structure Design
Equipped with anti-refill valves, breakable locks, or anti-reverse steel balls. Once opened, the cap cannot be resealed, completely blocking counterfeit and refilled liquids from re-entering circulation.
2.Aluminum-Plastic Composite for Dual Protection
The aluminum shell is strong and pressure-resistant, and its surface can be customized with brushed textures, anodizing, screen printing, or hot stamping. The food-grade PP/PE liner ensures safe contact with liquids, offering high heat and corrosion resistance.
3.Standardized Size with Excellent Compatibility
With a size of 33mm × 47mm, the cap fits most high-end glass and plastic bottles on the market. It also supports automated capping, improving packaging efficiency.
4.Advanced Anti-Counterfeiting Features
Optional integration with laser codes, QR tracking systems, hidden security marks, or RFID chips. Supports connectivity with enterprise traceability platforms for full-chain monitoring from production to retail.
5.Eco-Friendly and Cost-Efficient
Separation-friendly recycling: While not refillable, these caps are easier to process industrially and cost less than reusable alternatives.
Economic advantage: Ideal for high-volume industries such as pharmaceuticals and beverages, with unit costs as low as $0.01.
