Cap Liners: An Essential Guide to Protecting Your Valuables

Cap liners are essential components of many packaging and sealing applications. They provide a protective barrier between the product and the closure, preventing leaks, contamination, and evaporation. Cap liners are available in a variety of materials, each with its unique properties and benefits.

Benefits of Cap Liners

Cap liners offer a number of benefits, including:

Leak prevention: Cap liners create a tight seal between the closure and the container, preventing leaks and spills.

Contamination protection: Cap liners protect the product from contamination by outside elements, such as dust, moisture, and bacteria.

Evaporation prevention: Cap liners prevent evaporation, which can lead to product degradation and loss of potency.

How to Use Cap Liners

Cap liners are easy to use. Simply place the cap liner on the inside of the closure before screwing it onto the container. The cap liner will conform to the shape of the closure, creating a tight seal.
