FAQ

Frequently Asked Questions About Pressure Sensitive Vent Liners

Learn how Ventrase pressure sensitive vent liners provide breathable sealing, pressure equalization and waterproof protection for industrial packaging.

What are pressure sensitive vent liners?

Pressure sensitive vent liners are breathable sealing components that combine an adhesive layer with an ePTFE membrane. They attach to the inside of container caps and allow controlled gas exchange while preventing liquid leakage.

Do pressure sensitive vent liners require induction sealing?

No. Unlike induction vent liners, pressure sensitive vent liners use an adhesive bonding system and do not require induction sealing equipment, making them suitable for flexible packaging operations.

What industries use adhesive vent liners?

These vent liners are commonly used in chemical packaging, agrochemical containers, fertilizer bottles, nutritional products, cosmetics and other applications requiring pressure balance.

Are pressure sensitive vent liners waterproof?

Yes. The hydrophobic ePTFE membrane structure provides waterproof protection while maintaining high gas permeability for pressure equalization.

Can Ventrase customize vent liner sizes?

Yes. Ventrase provides customized diameters, airflow levels, adhesive structures and membrane options according to different bottle designs and packaging requirements.

How do I choose the correct vent liner?

Selection depends on container volume, chemical compatibility, expected pressure changes, cap design, storage environment and required airflow performance.
