Applications
Detailed Information
Oval air punch blades create wider ventilation areas in elliptical profiles compared to round punches. Manufactured from the same AISI 440C (1.0% C, 17% Cr) 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: 1.0% carbon + 17% chromium composition delivers both HRC 58-60 hardness and superior corrosion resistance in martensitic structure. Electropolished to Ra ≤0.3 µm food-grade surface.
Compatible Machines: Multivac, Tiromat, GEA, Opack, Betapak, Alcan, Ulma, Variovac.
