GORE™ Packaging Vents: Liner Products
Vented liners that provide liquid resistance and airflow for containers
Vented cap liners from Gore simply and easily replace non-vented liners. These closure vents help to equalize pressure and prevent contamination for containers and bottles that could otherwise bloat or collapse.
Induction Liners are made with an additional 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 Liner Products from Gore for container venting:
-
Integrate easily into existing cap configurations and are compatible with standard closure lining production equipment
-
Wide array of vent sizes and ready-to-use components which simply replace any existing liner material
-
Optional foil liner which can be induction sealed to container
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
-
Offer the best combination of liquid resistance and airflow, even after exposure to liquids containing organics, surfactants, oils and solvent based liquids
-
Manage differential pressure within a container
