We manufacture vented liners for a variety of applications, and provide design and engineering capabilitiesto convert virtually any closure to a vented format. We specialize in creating unique product solutions quicklyand efficiently.Circumvent and AirFoil are patented vented liner systems developed to eliminate the swelling or collapsing of plastic containers by allowing them to “breathe” without leaking. These innovative vented liners replace traditional foam, pulp, paper or foil liners and provide a leak-proof closure.we convert standard foam liner products to a vented format by utilizing various breathable materials including expanded polytetrafluoroethylene (ePTFE) membrane. This membrane has a unique microporous structure that repels liquids yet safely allows the free passage of air to maintain equalized pressure within a closed container.
Our products have the flexibility to meetdifferent customer applications and requirements.
AirFoil feature:• Broad chemical compatibility• Resistance to back-off• High liquid intrusion rating• Custom design capabilities
Prevents container distortiondue to:• Product off-gassing• Oxygen scavenging• Changes in temperature• Changes in altitude
