Liner Options

These liners are sized to fit industry standard 20mm neck finishes. Due to the variation in neck finish dimensions, particularly with glass bottles, we recommend testing the compatibility of liners with your bottle/cap combination.

Foam Liner (F-217® .035″ 3-Ply Co-extruded Foam Liner)
F217 liners are made of three layers: a thin soft polyethylene foam core sandwiched between two clear layers of LDPE film. F217 has become the industry standard due to its all purpose compatibility, resilient, compressible seal, cleanliness (no pulp dust) and economy. F217 liners are taste and odor resistant, and have a low moisture transmission rate, meaning they prevent moisture from entering the bottle and affecting products. F217 is a brand-name and tends to be used interchangeably with foam liner. However, F217 actually performs better than a regular foam liner. This liner does not create an airtight seal.

Pressure Sensitive Liner (PS-22 .020″ Polystyrene Foam Liner – Printed)
Imprinted with “Sealed for Your Protection” in Black.
Structurally similar to a foam liner, pressure sensitive liners have adhesive on one side, designed to stick on to the rim of a container. When a container is closed and pressure is applied to the cap (and in turn, the liner), the adhesive becomes activated, which creates a seal. Pressure sensitive liners provide an extra level of protection in that it actually creates a seal that sticks to the rim of the bottle. Pressure seals are not considered a form of tamper evident seal. They do not work well with liquids, especially oils. They can, at times, work with thick liquids such as creams and sauces.

Heat Induction Seal (HIS) Liners – 2 Piece
Induction liners are a popular choice when a tamper evident air tight seal is needed. It also works well with liquid products. HIS liners are available with either a Pulp (paper) or Foam (polyethylene) backing that remain with the cap. “Tamper Indicating” or “Welded Seal” liners provide a tamper-evident bond to the container and are noticeable if removed. The “Clean Peel” liners provide an aggressive bond with clean peel removal but are not tamper-evident. An induction machine is required to apply the liner. Printed liners are imprinted with “Sealed for Your Protection” in Black.
