The 68W59P is a 58mm polystyrene foam aluminum foil (Uni-Foam™ PS-F1) liner insert with a pressure sensitive and torque activated 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. Ideal for packaging dry products from spices, food, to medicine. These liners are not recommended for liquids and oils or any wet product. The Uni-Foam™ PS-F1 pressure sensitive foil liner 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 seal peels easily from container
  • Indicates tamper evidence
  • Protects against oxygen, outside flavors, and moisture
