Types of 28mm Beverage Aluminum Caps

Screw Caps	Among the most commonly used types, screw caps connect with the bottle via threading to provide a reliable seal. Typically equipped with a tamper-evident band that breaks upon first opening, these caps allow for easy opening and resealing by consumers.
Tamper-Evident Caps (ROPP - Roll-On Pilfer-Proof Caps)	Made from aluminum, ROPP caps are formed using a roll-on process that creates a tight seal on the bottle neck and includes a tamper-proof ring. These caps are commonly used for wine, spirits, and mineral water, offering excellent anti-counterfeit protection. They are compatible with various neck finishes, including 28mm PCO, 28mm Alaska, and 28mm BPF.
Disc Top Caps	These feature a pressable disc top that allows for one-handed opening, ideal for drinks requiring quick and easy access.
Combination Caps (Aluminum PP Caps)	Combining aluminum’s durability with polypropylene’s versatility, these caps provide secure and tamper-evident seals. Commonly used in pharmaceuticals, food, and cosmetics packaging.
