Choosing a Cap or Closure

Choosing a Cap or Closure

There are several things to consider when choosing a plastic cap for your products.

Container Size & Construction

First, you need to know the precise neck size of your bottle, jar or container and what type of plastic it is made of—ask your packaging manufacturer.

Cap Size, Depth, and Feel

Then you need to select a compatible sized closure. Pano Cap offers standard 400 finish plastic caps from 28mm- 120mm, as well as 28mm flip caps. See our full selection of sizes.

You will also need to choose a shallow or deep skirt for your cap. The height of your bottle neck may dictate the depth of your closure. With shorter necks you can only use shallow skirts. Closure depth impacts the look and feel of your package and affects how it is capped. Our sales staff can walk you through the right choice.

Another feature that shapes the look and feel of your package is the texture of your closure. Depending on your product and your end-users, you could choose fine ribs, coarse ribs (which make gripping and opening easier), or a smooth surface.

Tamper Evident Closures

Tamper Evident caps deter opening products before purchase, prevent removing or tampering products, improve closure strength during shipping, protect the liner and provide clear evidence of tampering. Pano Cap pioneered the first Tamper Evident (TE) closure in 1983 and continues to provide the widest selection of innovative secure closures in North America. TE closures come with shallow or deep skirts.

Tamper evidency is a regulatory requirement for supplements and other nutraceuticals, as well as medications and other pharmaceuticals. They are often used for food or beverages such as ketchup, mayonnaise, coconut oil, salad dressing, nutrition powders, milk or juice.


Liners are the material that sits between a closure and your bottle or jar. Many dry, solid products don’t require a liner, while liquids, powders, and pastes do. Liners help with proper sealing of products and often improve the fit of a cap. Liners touch your products; therefore, it is critical that they are chemically compatible. Choosing the wrong liner could shorten shelf life or lead to leakage during shipping.

Pano Cap offers the following liners:

  • Foam (generally used for liquid products)
  • Venting (best for dry products that require ventilation)
  • 1-piece heat induction liners (foil, creates tamper evident packages)
  • 2-piece heat induction liners (foil, creates tamper evident packages and the secondary liner prevents leaking after the cap is re-applied)

Pano Cap heat induction liners are available in Full Weld Seal and Easy Peel. Our liners come in round cut and tabbed options. Tabs help to keep the liner in place during the capping process and give your customers something to grasp as they remove the liner.

Specialty Decoration Options

To enhance the attractiveness of your packaging, Pano Cap offers custom embossing (raised design or lettering), debossing (recessed design or lettering), and In Mold Labelling—a new process where labels are molded directly into the caps to avoid fading, scratching, tearing and moisture damage.
