Custom Long Serrated Knife for Packaging

Custom Long Serrated Knife for Automated Packaging Equipment

Our custom long serrated blade is built for automated packaging stations, food packaging lines and film heat-sealing and cutting machines. The extended-strip geometry, premium hardened steel and precision-ground teeth keep cutting performance steady through continuous heavy-load operation.

We customize everything: overall length, tooth geometry, mounting hole layout, blade thickness and raw material. As a custom packaging cutter blade it makes neat, chip-free cuts in plastic films, multi-layer composite foils and pouches — a common sight across modern packaging plants.

Core Product Benefits

Extended Strip Design Made for full-width slitting, it fits large-format automated packaging machines and non-stop production runs.	Custom Serrated Tooth Geometry Tooth shape, spacing and depth are tuned to your material for the best cut across different films and packaging substrates.
High Hardness, Low Wear Vacuum heat-treated high-grade steel reaches HRC 58-68 with good fracture toughness and a long service life at high speed.	Fully Tailored Manufacturing Set overall size, cutting span, mounting holes, thickness, surface treatment and edge profile to your actual needs.
Clean, Burr-Free Cuts Precision CNC grinding keeps every tooth uniformly sharp. Films and pouches cut clean — no warping, no burrs, no sticking.	Complete OEM & ODM Workflow We work strictly from your drawings, physical samples or machine spec sheets to build drop-in replacement toothed blades for packaging equipment.

Frequently Asked Questions

Can you make extra-long custom serrated blades?

Yes. We specialize in custom-length serrated strip blades from 100 mm to 1500 mm, all made to your drawings and machine specifications.

Can tooth patterns and hole layouts be modified?

Yes — every key parameter: tooth profile, tooth gap, hole layout, thickness, overall length and surface finish to your technical requirements.

Do you offer samples for machine validation?

We supply pre-production samples to your specs so you can test on the real machine — fit and cutting quality — before the bulk order.

What materials can we choose from?

HSS, D2 tool steel, stainless steel and cemented tungsten carbide. Pick the grade that matches your packaging media and working conditions.
