Induction liners are available in one-piece and two-piece composition. The one-piece type mainly consists of foam backed and thin paper backed. After the sealing process, the entire liner will be completely removed from the cap.

Also, the one-piece type is more malleable. We can customize the printed logo, customize the pull-out ear for easy opening.
How to choose induction foil liner?
Selecting the best induction foil liner for your product is dependent on several factors, such as the container's material, caps design and application.
Plastic containers with continuous thread plastic caps produce the most consistent seal with the least challenges. Some glass containers may need to be treated in order to properly accept an induction seal. Sealing with metal caps is possible, but can pose several problems. As the induction system heats the foil liner, it also heats the metal cap, which can remain hot for a while. This can become a safety hazard and could also melt the threads if used on plastic containers.
 | Two piece induction foil liner has thick backing like cardboard or pe foam. The backing could Fill the gap between the lid and the bottle lip,and place a role of secondary anti-leakage after the bottle lip is opened. Therefore, it is usually used in the packaging of food, snacks, biscuits, medicines, especially chemicals and pesticides. |
The one piece type has a good appearance, with a total thickness of 0.2-0.4mm, and can flexibly print logos of various beautiful colors to improve product quality. And can produce clean peel type, so it is usually used in the packaging of high-value items such as health care products, beverages and cosmetics to enhance the added value of products. |  |
