Closures are a crucial part of the packaging process. Although they can be seen as a fun decorative element, they actually perform several vital functions depending on the type of closure. Need more info about the benefits of closures? We have your guide to all the basics here!

Closures seal many types of packaging containers, such as bottles, canisters, and jars. They perform different functions depending on the contents they are protecting and the container they are sealing. A closure is used to reclose the container for the reuse of the contents inside, or to assist in dispensing the product. It can also provide a barrier to dirt, oxygen, and moisture.

Are there different types of closures?

There are many different types of closures that perform a variety of functions. Some common types of closures include continuous thread closures (CT), disc top caps, child resistant (CRC) closures, pumps, and sprayers. A CT cap is your basic closure that can be easily sealed and resealed. Disc top caps allow the user to dispense product without having to remove the cap. CRC Caps are child resistant closures designed to keep children from opening the content. Pumps and sprayers allow the user to dispense an equal amount of high viscosity product with each use.

A container’s neck finish holds the cap, stopper, or closure with protruding threads. A container and its corresponding cap must have matching finishes. View the chart below to find out how bottle closures and neck finishes are sized.

We have an ample number of closure colors available. Depending on your branding needs, we can help you find what you are looking for.

When you read about closure size, it is a reference to the diameter of the closure. They are sized from the beginning of one side, across the closure, and end with the outermost point of the thread. Our standard sizes range from 18mm through 120mm.
