How Aluminum Foil Vent Liners Work
The vent liner balances container pressure by allowing controlled gas transmission while maintaining liquid sealing protection.
01 Pressure Change
Temperature variation or chemical reactions may create internal pressure changes.
02 Gas Exchange
Gas molecules pass through the microporous ePTFE membrane.
03 Liquid Blocking
Hydrophobic membrane structure prevents liquid leakage.
04 Pressure Balance
Container deformation and swelling risks are reduced.
Waterproof Breathable ePTFE Technology
Expanded PTFE (ePTFE) membrane contains millions of micropores, providing high airflow, waterproof protection and chemical resistance.
Microporous Structure
Millions of microscopic pores create efficient gas transmission channels.
Waterproof Performance
Hydrophobic structure blocks liquid penetration during operation.
Chemical Compatibility
Suitable for demanding industrial packaging environments.
