Understanding the Differences Between PS22 and Induction Lined Closures


SKS offers a wide selection of cap liners within our metal and plastic caps. When choosing between PS22 and induction liners, many factors may come into consideration. Below is an in-depth comparison of PS22 and induction lined caps to assist in your decision and help you to find the right closure for your products' unique packaging needs.


Application of Liners

Liner Application Method


The method of application is the primary difference between PS22 and induction lined caps. PS22 liners are installed within the caps and can be sealed to the top of the bottles or jars without the requirement of additional tools or equipment. After the container has been filled, screw the cap on tightly, and leave in place for 24 hours. The seal will remain in place, helping to maintain the freshness of your product.

Induction lined caps are also sold within the caps, but they require use of an induction sealing machine for activation. SKS has created a helpful how-to video and guide on understanding how induction sealing works, to help in your initial purchasing and installation process.

Types of Seals



Types of Seals



Induction seals are one time use seals, and after their initial removal they will not re-seal. PS22 liners are not considered tamper evident since the liners can be resealed after the first application sometimes. For this reason, testing your products with the seals before a full production run is highly suggested.

Induction liners produce an airtight, hermetic, and leak proof seal, with added capabilities to assist in preserving freshness and shelf life.

PS22 and induction liners assist primarily in maintaining the freshness and integrity of your products, but there are also other benefits to including them in your product packaging. Induction seals provide customers with peace of mind in knowing that your containers have not been previously opened, as well as protection from spills and leakage during shipment and storage. Including liners can also demonstrate an added level of care to new and returning customers.
