The one-piece induction liner consists of a combination of high density polyethylene (PE) foam or paper, Aluminium foil and where required a protective barrier film with a matching sealing layer to suit the material properties of the container. Somewhere here is a PET film as a thermal barrier between the PE foam and aluminum foil.

Features:

1. The backing material is pretty thinner than which of two-piece induction liner
2. All the material construction adhere together as whole liner after sealing
3. As one-piece liner is disposable, with a foam liner in bottle cap is recommended to reseal the bottle after opening

Benefits:

1. Tamper-evidence: The seal provides clear evidence if the product has been opened before use
2. Leak Prevention: It prevents leakage of the contents, maintaining the product’s integrity during transportation and storage
3. High sealing efficiency: with an automatic induction sealing machine, the production liner can output 200~400 bottle per minute
4. Firm protection for the sealing, as there is backing material on the top of the sealing layer
5. Various backing materials, providing customers with a variety of sealing texture experiences. For example: using PE foam, it can have a puncture-resistant effect, while using PS foam as can make the liner easier to break through the seal. Using white cardboard paper as backing can also apply for various printing exquisite patterns or logos for customers.
6. For the sealing layer, one-piece induction liner usually use easy-peel sealing film, so that end-user can peel the seals off easily

Application:

One-piece induction liner is typically used in food, cosmetics product, beverage, pharmaceuticals, oil, and chemical products
