A PS22 liner is made of .020”thick polystyrene foam disc with an EVA-wax type adhesive that is released when the closure is properly torqued onto the container. The liner is designed to stay in place even after the cap has been removed. These liners will adhere to both plastic and glass bottles and jars. These liners provide a one-time seal to be removed by the end user. The benefit of this type of cap is that no secondary equipment is required to apply them.

While these seals when properly applied can create a moisture barrier for keeping products inside dry, they are not considered by the FDA to be tamper evident.

Suggested Product Uses: dry products, pharmaceuticals, nutraceuticals, candy, and spices.

Not good with: oil or other liquids.

Note: Keep liners away from direct heat and sunlight.

How to apply:

1. Allow liners to adjust to your process room temperature for 48 hours. Temperature should be between 60°F to 80°F.
2. Wipe the lip of the container with a clean cloth. If lip is not clean the liner will not adhere.
3. Screw closure with PS22 liner all the way down onto the container. Failure to screw closure all the way down may result in a poor seal.
4. Let sit for 24 hours to allow liner to fully adhere to container. We recommend that samples be purchased for testing with your specific application.
