Induction 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.
The GORE® Universal Liner is an induction liner for agrochemicals that is engineered with advanced roll-off properties and a wide induction sealing window for easier induction sealing.
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
- Easier induction sealing due to the wide sealing window engineered into the GORE® Universal Liner
- Advanced roll-off properties of the GORE® Universal Liner help to stand up to aggressive solvents like N-Methylpyrrolidone (NMP) and Solvesso™ without leakage, liner delamination or degradation in venting performance
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
