Custom Serrated Blades for Packaging Machines

Serrated Packaging Machine Blades Built for Continuous Production

Dekeer serrated blades are ground from hardened HSS, D2 and stainless steel to keep a tooth edge sharp through millions of sealing and cutting cycles. Each tooth profile is matched to your machine and material, so bags separate cleanly instead of stretching, tearing or leaving ragged tails on the line.

From VFFS and HFFS baggers to slitter rewinders, our toothed knives run at full production speed with fewer blade changes. Vacuum heat treatment locks in hardness of HRC 56-65, cutting unplanned downtime and stretching the service interval between sharpenings.

Main Benefits

Tooth Profiles Ground to Order Pitch, depth and angle of every tooth are made to your drawing, giving maximum abrasion resistance and a longer working life.	Stable Cutting at Full Line Speed Balanced tooth geometry keeps cuts clean and consistent on high-speed baggers, wrappers and slitting stations.
Long-Run Wear Resistance Wear-resistant steel holds edge quality across long production runs of film, foil and laminate, reducing changeovers.	Clean, Fray-Free Separation Tightly controlled tolerances mean every tooth bites the same, so packaging seals stay straight without fraying.
One Blade, Many Materials BOPP, PE, PET, laminates, kraft paper and nonwovens — we match the tooth form to your substrate and machine model.	OEM/ODM Support From Drawings Send a drawing, sample or machine model — we produce matched blades for flow wrappers, VFFS/HFFS machines and slitter rewinders.

Case Sealing & Tape Cutting

Long serrated knives for carton sealing heads, adhesive tape cutters and secondary packaging stations across fulfillment and logistics lines.

FAQ

Which industries use your serrated packaging blades?

They run on food packaging lines, film extrusion and converting plants, e-commerce courier bag production, paper mills and general logistics packing stations.

Can you match blades to our machine model or drawing?

Yes — send us a drawing, a worn sample or just the machine brand and model, and our engineers will produce a matched tooth profile and mounting hole layout.

What is the lead time for custom serrated blades?

Stock sizes ship in 7–15 days. Fully custom toothed blades take 15–25 days depending on profile complexity and order quantity.

Can we test samples before placing a bulk order?+

Yes. We supply sample blades for on-machine trials so you can verify fit, cut quality and service life before committing to volume.
