Keep the Right Things In
Keep the Wrong Things Out
The heart of a vented package is the membrane. Think of membrane like a window screen: it keeps out what you want to filter, yet allows air to flow through. The smaller the pore size (mesh in the screen), the smaller the particles/liquid it can hold back.
M-Industries Vented Liners
All of our vents are hydrophobic, or water-repellant. But to hold back oil-based products, your vent must be made with an oleophobic (or oil-repelling) membrane. M-Industries oleophobic membrane is superior to any in the industry due to a patented plasma process that coats each fiber in the material rather than smothering it in an oleophobic bath. Our oleophobic membrane allows more airflow for oil-based products than any other membrane while containing even the most aggressive contents.
