Selecting a Lids, Bottle Caps & Closures

When selecting a closure for your container, there are many factors to consider in terms of material, size, shape, use and appearance based on specific usage needs and container characteristics. For example, how the product should be dispensed, whether the package needs additional protection and the overall style you want to achieve. As always, be sure to test your products with packaging and closures to ensure compatibility.

Neck finishes

It is important that your caps fit correctly on the bottle or jar neck finish to obtain a proper seal. Threaded or continuous thread closure sizes are indicated by two numbers separated by a hyphen or slash (e.g. 20/410, 20-400). The first number (e.g., 20) is the millimeter diameter measured on the inside of the cap opening or on the outside of the bottle threads. The second number (e.g. 410) refers to the thread pattern. For more information, please visit our Cap and Neck Finishes information page.

Gasket Type

Selecting a liner is an important part of the bottle cap selection process. Some liners tend to be more resistant to chemicals than others, while other liner material types are better suited for moisture resistance. Some of the more popular liner types include PE, PV (polyethylene based), PS22 (plain or printed pressure sensitive), induction liners and Polyethylene Seal™ cone liners. Always test your products with the liner of your choice to ensure they are compatible.
