Designed exclusively for corrugated paper slitting, these industrial-grade circular blades feature thickened high-hardness alloy steel construction, CNC precision grinding, and burr-free sharp edges. The vacuum heat-treatment process boosts hardness (HRC 58-62) and wear resistance, enabling consistent, smooth cuts even in heavy-duty, continuous operation. Rust-proof and fatigue-resistant, they excel at slitting corrugated paper, cardboard rolls, and packaging materials without damaging the substrate. Perfect for corrugated box manufacturing and packaging industry production lines, the blades minimize downtime, reduce material loss, and extend service life, providing cost-effective, high-performance slitting solutions for businesses seeking reliability and efficiency in corrugated paper processing.
