The ePTFE membrane allows gas molecules to pass while blocking liquid penetration.
Package Protection
Balanced pressure helps reduce swelling, collapse, and leakage risks.
Waterproof Breathable ePTFE Membrane Technology
The microporous ePTFE membrane is the key functional component of Ventrase vent liners.Its unique structure allows air and gas transmission while preventing liquid penetration, providing continuous pressure equalization for sealed packaging systems.
Microporous Structure
Millions of microscopic pores create a breathable pathway while maintaining waterproof protection.
Waterproof Performance
Blocks liquid entry during storage, transportation, and environmental exposure.
Gas Transmission
Allows controlled airflow to balance pressure inside packaging containers.
