28mm Water Bottle Caps

This product is a 28mm plastic tamper-evident screw cap for PET bottle packaging of bottled mineral water, purified water, and certain beverages. The cap is made of food-grade PP and comes with a standard tamper-evident tear band; once opened, the tear band separates from the bottle, making it easy for end consumers to identify whether the product has been previously opened. Bottled water factories typically match and search for caps by Neck Finish standard when purchasing. This product covers the two most common 28mm neck finish standards in the industry, PCO 1810 and PCO 1881, and can be directly matched to the customer's existing preform molds or blow-molding equipment without the need to redevelop the neck structure.
