Twist-Off Aluminum Caps: Enhancing Safety and Tamper Protection
Twist-off aluminum caps are widely used for sealing bottled products such as wine, spirits, beverages, food, and chemicals. These caps are made from aluminum alloy with an EPE liner, and are available in a variety of specifications, such as 30×35mm, 30×60mm, 30×44mm, 29×34mm, 25×43mm, and can be customized according to customer requirements.
Security by Design: Tamper-Evident Mechanism
These caps feature a special tamper-evident ring with a double-tear, single-break structure. The cap body includes circumferential cuts, bridges, and a connecting band, while the ring has a vertical tear line that intersects with the circumferential cuts.
Upon opening, the tamper-evident ring splits into two spirals that twist in opposite directions, clearly showing signs of first-time opening—a strong deterrent against tampering or refilling.
