Venting Liners and Caps, Gas Escapes While Liquid Stays Sealed
A venting liner carries a one-way membrane and a press-fit vent lets gas out without letting liquid through, so agrochemical and fertiliser bottles do not bulge or burst.

Overview
Pressure relief for containers that build gas
Some contents release gas as they sit, especially in heat or transit. Agrochemical and fertiliser bottles bulge, and at worst burst. A venting liner solves this with a breathable membrane that lets gas out while the liquid stays sealed inside.
The membrane is chemically resistant, holding up against pesticides, fertilisers and solvent-based liquids. Choose a venting liner that seals onto the bottle mouth, or a ready-to-use press-fit vent cap. Where a standard induction liner would trap pressure, a venting liner releases it and keeps the tamper-evident seal intact.
How it is built
A layered structure, drawn to spec
A vented liner adds a breathable membrane to the foil build. Gases escape as pressure builds while the liquid stays sealed inside, protecting containers from bulging or bursting.
