What Is the Difference Between Twist-Off Closures and Lug Caps?

Q1: What are Twist-Off Closures?

A: Twist-Off Closures are a type of bottle or jar closure designed to be opened and resealed simply by twisting. They are widely used in the food and beverage industry because they combine consumer convenience with reliable sealing performance. Commonly found on glass jars for sauces, jams, juices, and condiments, twist-off closures ensure freshness, safety, and ease of use.

Q2: How do Lug Caps relate to Twist-Off Closures?

A: Lug caps are a specific type of twist-off closure. A lug cap uses several short threads (called “lugs”) on the inside of the metal cap. These lugs lock onto the threads of a glass bottle or jar neck, creating a secure seal with just a partial turn. In other words:
👉 All lug caps are twist-off closures, but not all twist-off closures are lug caps.
