What is Cap and Closure?

Caps and closures are components used to seal containers and control access to their contents. They are available in designs such as screw caps, snap-on closures, flip-top caps, and dispensing closures. Common materials include plastic, metal, and combinations of materials. They are widely used with bottles, jars, tubes, cans, and other containers. Selection depends on sealing performance, product compatibility, dispensing requirements, and consumer convenience.
