Tungsten carbide pentagonal knife blades are highly specialized industrial cutting tools engineered primarily for high-volume conversion machinery, sack making, and woven bag production. Manufactured from solid sintered tungsten carbide (often bonded with a cobalt matrix), these blades combine extreme hardness with a unique five-sided geometry to provide five distinct, rotatable cutting points on a single piece of hardware.

Key Applications & Industries

Packaging and Bag Production: Extensively utilized in the automated manufacturing of woven polypropylene (PP) sacks, multi-wall paper bags, and industrial packaging like cement bags.
Film and Foil Slitting: Used for clean, burr-free slitting of plastic films, laminated composites, and aluminum foils.
Textile and Rubber Processing: Integrated into rotary and automated slicing machines to handle tough, dense, or abrasive synthetic fibers.

Performance Characteristics

Attribute	Specification Details
Material Composition	Solid tungsten carbide, frequently containing a 15% Cobalt binder to improve impact resistance and prevent brittle chipping.
Hardness Rating	Reaches up to 89–94 HRA (or roughly 71 HRC), vastly outperforming traditional high-speed steels (HSS).
Indexable Geometry	The five-pointed pentagonal design ensures that when one edge finally dulls, the blade can be rotated to a fresh cutting point, providing 5x the operational lifespan before requiring replacement.
Maintenance Profile	Requires highly specialized diamond grinding wheels or diamond lapping films if re-sharpening is attempted, as standard sharpening stones cannot cut the carbide matrix.

Film manufacturers must be 100% reliant on the sharpness of the blades. The companys film cutting blades are available for cutting PP, PE, PET,BOPP films and etc., it also can be used for cutting metal films such as plastic films, capacitor films, and lithium battery diaphragm. The blades we produce are not only sharp, but also able to keep the sharpness lasting. Please experience it for yourself!Highest sharpness and precision,Each blade has an extremely long life.Increased productivity due to increased cutting speed and reduced number of blade changes.The trimming is clean and does not form raw edge.
