MS® PTFE Venting for Packaging Description

Improve Your Equipment’s Reliability and Durability

Membrane Solutions’ packaging vents use superior ePTFE membrane structures to enable airflow and prevent leaks for even the most highly concentrated liquids. It is designed for use with solvent or water-based solutions, granular or powder chemicals, food and beverage, or for use with low surface tension fluids such as oils, detergents, surfactants, and more.

Features & Benefits

  • Rapidly and continuously equalize pressure differentials
  • Rapid response to sudden changes in altitude, ambient temperatures or pressures
  • Excellent roll-off prevents even viscous formulations from blocking airflow
  • Quick recovery of venting after contact with high-viscosity or low surface-tension liquids
  • Exceptional liquid resistance prevents “wetting out” and leakage of contents

Typical Applications

  • Agricultural packaging:pesticides, herbicides
  • Household packaging:cleaners and detergents
  • Industrial packaging 

MS® PTFE Membrane Format

•A4 and A5 sheets
•Die cut parts with adhesive backing

Assembly Options for MS® PTFE Vents

  • Ultra-Sonic welding or heat sealing require welding of the vent material directly to the cap or the liner.
