Applications
Detailed Information
Oval air punch blades create wider ventilation areas in elliptical profiles compared to round punches. Manufactured from AISI 440C martensitic stainless steel.
Oval Advantage: Elliptical geometry provides 40% more gas passage surface in the same film area. This feature is preferred in MAP (Modified Atmosphere Packaging) requiring rapid gas exchange.
440C Properties: Martensitic structure delivers both HRC 58-60 hardness and superior corrosion resistance. Electropolished to Ra ≤0.3 µm food-grade surface.
Compatible with all major thermoform and vacuum packaging machines.
