The 68W58L is a 58mm polystyrene white foam coated (PS-22) liner insert with a pressure sensitive coating. Pressure sensitive liners create an actual seal, providing an extra level of protection compared to a basic foam liner. They are best for dry products and can at times, work with thick liquids such as creams and sauces. Generally, these liners are not recommended for liquids and oils. Material is a styrene foam innerseal coated with a torque activated coating. It has adhesion to glass and plastic bottles with metal or plastic caps.

Key Benefits:

  • Polystyrene foam liner coated with torque-activated adhesive
  • Requires no heat induction equipment
  • Seals to most container materials with varying degrees of adhesion
  • Single-use foam seal peels easily from container
  • Indicates tamper evidence
  • Recommended for sealing dry products

Cap Liner Type:

Pressure Sensitive Liner (Pressure Seal 020 Pressure Sensitive Polystyrene Foam Liner - Printed)
Imprinted with "Sealed for Your Protection" in Red.
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.
