twistoff

Twistoff is a term used in packaging to describe a type of container closure that uses screw threads and is opened by twisting the cap off the container. It is commonly employed on beverage bottles, condiment jars, and other consumer-packaged goods. The term emphasizes the action of turning the cap and the closure’s ability to be resealed after opening.

Most twistoff closures consist of two main components: the cap and the bottle neck threads. Caps can be metal or plastic and may include a liner to create a hermetic seal. A tamper-evident band or seal is often incorporated to indicate prior opening. The closure provides resealability and can be reapplied after opening, though repeated torque and improper tightening can compromise the seal over time.

Twistoff closures vary in diameter and thread pitch to fit different bottle sizes. They are widely used on soft drinks, water, sauces, and other products where consumer convenience and the option to reseal are valued. In production settings, twistoff lids enable high-speed automated capping and are compatible with recyclable materials, contributing to streamlined manufacturing and packaging workflows.

The term twistoff is sometimes used as a brand name or product line designation by manufacturers, and in some cases the term is used generically to describe any screw-on closure. It is important to distinguish twistoff from other closures such as crown caps, which require a separate tool or opener to remove.
