Seal liner questions,
answered.

Start with four questions. Do you need visible tamper evidence? Will the container be opened and closed repeatedly? Does the product release gas or build pressure? And what is the container made of, and do you have heat-sealing equipment? The answers narrow six products down quickly — our seal selection guide maps each need to the products that meet it.

A 1-piece seal is a single liner that bonds to the container and comes away completely when opened, leaving nothing in the cap. A 2-piece seal adds a separate backing wad that stays inside the cap after the foil seal is removed, so the cap still seals the container when it is closed again. Choose 1-piece when the product does not need resealing; choose 2-piece when the container is opened and closed repeatedly.

When the product releases gas or builds pressure after sealing. A vented seal lets that pressure release in a controlled way instead of straining the cap and seal.

Lift & Peel. It is an easy-open liner designed for the end consumer, and it peels away cleanly with no residue.

A liner fitted inside the cap that bonds to the container rim when the capped container passes under an induction sealer. The electromagnetic field heats the liner's foil, melting its sealing layer onto the rim. Our induction range is the 1-Piece IHS, 2-Piece IHS, Two Piece Induction Vented Seal and Lift & Peel.

No. Induction sealing heats the liner through the cap without contact, so the container is sealed with the cap already on.

It closes off the container opening itself rather than relying on the cap alone, which helps guard against leaks, tampering and contamination between filling and first use. Real-world performance depends on the container, product and sealing setup, which is why we confirm the specification for each application.

The seal is bonded to the container rim, so it cannot be removed and put back without it showing. Our induction seals and conduction seal are tamper-evident; EPE wads are not.

Both bond a liner to the container rim using heat. Induction sealing heats the liner's foil without contact, through the cap, using an electromagnetic field. Conduction sealing heats the liner by direct contact with a heated plate pressed onto it.

When your containers are HDPE plastic and you need a hermetic, tamper-evident seal — for example for hazardous chemicals, dairy, cultured milk or soy-based drinks.

Compressible polyethylene foam liners that sit inside the cap. They seal by compression when the cap is tightened, with no heat required.

No. They reseal every time the cap is closed but do not show whether the container has been opened. For tamper evidence, choose an induction or conduction seal.

Your container material and neck size, the product being sealed, your monthly volume, and whether you need tamper evidence, resealing or venting. If you are not sure, describe the application and we will work it out with you.

Yes — custom printing, non-standard sizing and material substitution are part of our custom solutions. Describe your container and what you need, and we will confirm what is possible.

It depends on the liner and size. Tell us the specification and volume you need, and we will confirm for that item.
