Chemical containers and packaging frequently experience internal pressure build-up due to temperature fluctuations and chemical vapor generation. This can cause container deformation, leakage of hazardous substances, or safety hazards.
SST-Porous® Aluminum Foil Venting Seal Liners solve these issues by continuously equalizing internal and external pressure. For lids with holes, gas passes directly through the liner and escapes via the holes. For lids without holes, gas travels through the liner to the area above the breathable membrane and is guided to the threaded position of the cap. In both cases, liquids, oils, and particles are effectively blocked.
Made with durable aluminum foil and oleophobically modified ePTFE membrane, these liners offer simple installation, long service life, and excellent chemical resistance. Available in various sizes to fit different container requirements.
SST is committed to providing professional venting solutions that enhance container safety, prevent leaks, and extend the service life of chemical packaging.
