Food and Package Cutting Solutions: Blades for Filling, Sealing and Finishing Lines

Blade solutions for food and packaging lines: toothed bag knives, rotary cutters and stainless food blades, with hygiene and coating guidance.

Packaging lines cut continuously: film at the sealer, bags at the filler, trim at the wrapper. Each station has different speed, product and hygiene demands, so a single blade type rarely fits all.

Bag Making and Filling Machines

Vertical and horizontal fill-seal machines use toothed or straight package cutting knives that work in pairs against a sealing jaw. Timing matters as much as sharpness — a knife that is a fraction out of phase tears instead of cuts.


Rotary Cutters for Continuous Film

Where the web never stops, rotary cutter blades shear against a fixed or counter-rotating edge. Tooth style defines the cut: saw teeth for aggressive tearing, fine teeth for clean bags, scalloped edges for crimp-free seals on laminated film.


Hygiene and Materials

Food contact zones call for stainless blades with smooth ground faces, and coatings must be food-safe. Our stainless steel food cutting blades guide covers grade selection for washdown areas in detail.
• Stainlessmartensitic grades balance edge holding with corrosion resistance • PTFE-type coatings reduce product sticking on adhesive-rich products • Mirror-polished faces help cleaning and inspection
