-Paper industrial knife involves various type like circular slitter knife, cut off blade, log saw blade, multi-edges bottom knife, rewinder knife, slotter knife, polar cutting knife, etc which with different shapes such as circular, straight, inserting, toothed and so on. And the application is to slitting, rewinding, perforating and guillotine cutting.

-Cut off blade is designed specially for corrugator cutting machines, with straight blades(rejection blades) or spiral blades based on your requirements. Generally, C45 steel is chosen as the main body material, and the cutting edge is HSS or TCT. Straight blades are generally used for lower - speed corrugators, while spiral blades are installed on high-speed corrugators.

-Corrugated Paper Blade is engineered for cutting corrugated paper board, which is about three, more or less layers of fluted (wave-shaped) paper sandwiched between flat linerboards. Popular brands are Fosber, Agnati, BHS, Isowa, Marquip, His Hsu, Mitsubishi, TCY, JS, K&H, Kaituo, and so on. LC knives could provide precise, efficient, and neat cuts during the production of corrugated boxes and packaging materials. It involves corrugated paper slitter knife, cut off blade, slotter knife, valve knife, bottom knife, spacer, and grinding wheel.

-Polar Paper Knife is a cutting blade specially engineered and manufactured for Polar cutting machines. LC polar cutting knives can be used in high precision industrial paper - cuttings.
LC polar cutting knife is made of CrWMn, HSS or TCT insert, with an excellent inserting technology, the original grains are more refined and highly resistant to chipping, and the blade has no defects of inserts peeling off or gaps. Thus LC polar knife could have a long service life with cutting paper precisely and smoothly.
The edge of the papers cut by our knife is clean and smooth without burrs, which improves the overall quality and appearance of the papers. In particular, If there is, it can fundamentally improve the quality of the subsequent printing process.
