Gas Permeability: Vent PE liners allow gases to pass through, maintaining optimal internal pressure and preventing packaging from bulging or collapsing.
Moisture Resistance: Moreover, they are a barrier to moisture. They can keep the contents of a bag from getting damp.
Durability: As liner material composed of polyethylene, vent PE liners are strong and hard to tear or puncture. Packaging's protective qualities are therefore assured.
