Liners

Create Tamper Evident Packaging that Breathes without Leaking

GORE™ Induction Liners are made with an aluminum foil seal to provide multiple functions in one compact solution. The aluminum foil can be high-frequency induction sealed to the opening of a container, providing a tight seal around the container edges for improved liquid seal and tamper evidence.


Realize the benefits of GORE™ Induction Liners for container venting:

  • Equalize pressure and prevent containers from bloating, collapsing or leaking
  • Enable the use of thin-walled, light-weight packaging to minimize packaging and disposal costs
  • Prevent liquid penetration and continue to vent even after exposure to liquids containing organics, surfactants, oils and solvents
  • Available in a wide array of sizes that simply replaces any existing liner material
  • Typically no design change necessary to existing cap
  • Flexible to work with- peelable or permanent welds for HDPE and PET bottles

The science behind the solution

GORE™ Packaging Vents offer the best combination of liquid resistance and airflow through the use of expanded polytetrafluoroethylene (ePTFE). The chemically inert GORE™ Membrane is designed to:

  • Prevent liquid penetration of chemicals with strong formulations and agressive additives
  • Equalize pressure in containers by delivering consistantly high airflow
  • Maintain container integrity
