Our patented 21-tooth twist-off crown cap allows tool-free hand opening, unlike traditional pry-off caps. Popular worldwide among breweries and liquor brands, it adopts food-grade ISO 9001 tinplate with leak-proof liner. Its uniform 21 serrations avoid gas leakage even after cold storage and long sea transit, and the brushed surface supports custom printing, hot stamping and embossing to match premium spirit & beer bottles.

Our 21-tooth twist cap features an optimized tool-free opening structure, fixing slipping and jamming issues common to cheap twist caps; users can twist it barehanded to boost your product repurchases. Its evenly spaced 21 serrations deliver balanced pressure for reliable leakproof sealing, fitting most beer and spirit glass bottles including thick-base custom ones for unified brand packaging. Backed by 29 independent patents covering opening, sealing and stamping tech, we supply full patent documents to help overseas buyers avoid packaging infringement risks and gain unique market competitiveness over standard pry-off caps.

Our 21-tooth twist-off crown caps fit all mainstream beverage packaging demands worldwide. They work perfectly on factory automatic crimpers for beer, soda and fruit liqueurs with reliable sealing. Matching premium thick-base liquor bottles, customizable caps build luxury gift sets for duty-free and high-end retail sales. Highly popular among global wholesale importers especially in Africa, the easy-twist design lifts retail sales greatly. Blank silver caps also support small trial orders for new private label brands with flexible logo customization.
