Serrated blades are defined by both the blade body and the tooth form. MEIRENTE reviews tooth profile, pitch, mounting details and cutting application together so a custom tape knife or serrated blade matches the approved drawing.
Toothed knives are used for adhesive tape, packaging, film, fibre, food and other materials where the tooth initiates or controls the cut. Tooth form should match the material, cutting motion and support provided by the machine.
Pitch, tooth depth, included angle, set direction and edge finish can be as important as overall blade size. Slots, holes and locating notches must be measured from agreed datums so the replacement knife sits correctly in the holder.
Provide a drawing when available. If only a sample is available, send clear images of the full blade, teeth, both faces and mounting features together with the equipment reference and material being cut.
For a custom review, send the drawing or sample dimensions together with the machine and application details you already have. Final specifications are confirmed before production.
Direct answers for blade buyers
Serrated blades are defined by both the blade body and the tooth form. MEIRENTE reviews tooth profile, pitch, mounting details and cutting application together so a custom tape knife or serrated blade matches the approved drawing.
Confirm overall blade dimensions and mounting-hole positions; tooth pitch, tooth profile and cutting direction; machine model and material being cut. Include the required quantity and any current cutting defect when available.
MEIRENTE reviews non-standard industrial knife requests from an approved drawing or sample. Final dimensions, mounting features, material, hardness and edge geometry are confirmed before production.

Blade selection by application
Compare serrated and toothed cutting applications by packaging material, feed method, tooth profile and the tearing, dust or incomplete-cut problem found on the machine.
Case and carton sealing equipment needs reliable tape penetration, repeatable cut-off and mounting geometry matched to the sealer mechanism.
Adhesive tape cutting performance depends on film reinforcement, adhesive transfer, tooth form and the way the tape is tensioned during cut-off.
Tooth pitch, tooth depth and edge condition must match the required tear initiation, perforation pattern and packaging material strength.
