Product Description

Key Features

• Premium alloy steel / high-speed steel material with vacuum heat treatment, stable hardness and strong toughness

• Mirror polished surface reduces friction, prevents film adhesion and dust buildup

• Precision CNC grinding for concentricity and edge consistency, ensuring stable high-speed operation

• Ultra-sharp cutting edge delivers clean, burr‑free slitting without film tearing or edge curling

• Food-safe surface treatment, suitable for direct contact with food packaging materials

• Good wear and rust resistance, long service life, reduced downtime for blade changes

Main Advantages
