PE Vent Membrane
PE (Polyethylene) vent membranes are cost-effective breathable solutions designed for packaging applications that require basic airflow, moisture protection, and pressure equalization.
They are widely used in agricultural chemicals, household products, and industrial containers where controlled ventilation and sealing performance are required.
Core Advantages
- Low-cost venting solution for mass production
- Stable airflow balance in sealed packaging
- Moisture and condensation control
- Compatible with chemical packaging systems
Typical Applications
Agricultural chemical packaging, detergents, household cleaning bottles, industrial liquid containers, and general-purpose vented closures.
What is PE Vent Membrane?
PE vent membrane is made from microporous polyethylene material that allows controlled airflow while blocking liquid water and contaminants. It is widely used in packaging systems where cost efficiency and basic protection are required.
Air Permeability
Allows controlled gas exchange to balance internal pressure.
Moisture Barrier
Helps reduce water ingress in packaging environments.
Packaging Focus
Designed for industrial and consumer packaging applications.
Cost Efficiency
Provides a low-cost venting solution compared to ePTFE materials.
Key Features of PE Membrane
Flexible Structure
Easy to integrate into sealing liners and packaging systems.
Chemical Resistance
Resistant to mild acids, alkalis and common industrial fluids.
Moderate Temperature Range
Suitable for standard storage and transport environments.
Easy Processing
Compatible with lamination, die-cutting and sealing processes.
