Dekeer’s Sealing and Cutting Machine Blades are designed for high-speed shearing, cross-cutting, and longitudinal cutting. With razor-sharp edges, superior wear resistance, and excellent straightness, these industrial blades ensure smooth, precise, and efficient cutting across a wide range of applications. They are widely used in plastic film, non-woven fabrics, pressure-sensitive adhesive (PSA) materials, laminates, and paper products. Dekeer supplies every packing machine blade type — cutter blades, sealing jaws, toothed shear knives and multi-hole cutter bars — to OEMs and converters worldwide.
- High-speed shearing, cross-cutting and longitudinal cutting — built for continuous packaging lines, not intermittent use
- Razor-sharp edge with excellent straightness for a clean, flat, burr-free cut on film, non-woven, PSA and laminates
- Selected grades — HSS, stainless steel or D2 — matched to the material you cut and the machine you run
- Made to your drawing, sample or machine model, including thickness, bevel angle and hole pattern

HSS vs Stainless Steel vs D2: Choosing the Right Grade
| Selection Factor | HSS (High Speed Steel) | Stainless Steel | D2 Tool Steel |
|---|---|---|---|
| Hardness | HRC 60–65 | HRC 52–57 | HRC 58–62 |
| Wear resistance | High — holds an edge on abrasive film and laminates | Moderate — chosen for hygiene rather than abrasion | Very high — excellent on hard, abrasive webs |
| Toughness | Good — resists chipping under shear shock | High — ductile and forgiving | Moderate — harder, so less shock-tolerant |
| Corrosion resistance | Low — keep oiled when stored | Excellent — rust-free in damp or washed-down areas | Low — requires protection |
| Edge retention | Long service life between regrinds | Shorter on abrasive stock, but easily reground | Longest between regrinds on hard material |
| Typical use | Film, non-woven, PSA, laminate and paper slitting | Food packaging, wet lines, medical and clean areas | Heavy-duty cross-cutting and high-abrasion lines |
| Relative cost | Standard | Standard | Higher |
Not sure which grade suits your line? Tell us the material you cut (film, non-woven, PSA, laminate, paper), the web width, the cutting speed and whether the blade is washed down — our engineers will recommend the grade and bevel that gives the best cost per cut.
Packaging Machine Blade Specifications
| Specification | Standard Range | Notes |
|---|---|---|
| Material grade | HSS (M2 / M35) · Stainless steel (420 / 440C) · D2 | HSS as standard; stainless for food and wash-down areas; D2 for heavy abrasion |
| Hardness | HRC 56–65 | Vacuum hardening and tempering, reported per batch |
| Dimensional tolerance | ±0.02 mm | Ground on CNC surface and profile grinders |
| Straightness | ≤0.10 mm per 1000 mm | Checked on a granite surface plate before dispatch |
| Bevel / edge angle | Single bevel 20–30° as standard | Double bevel, micro-bevel and serrated edge available on request |
| Surface roughness | Ra ≤ 0.4 µm on the cutting face | Polished to reduce friction and material build-up |
| Thickness | 0.2–12 mm | Matched to your cutting head, holder and material |
| Length / width | Made to drawing | From a few millimetres for slitting blades to long cross-cut bars |
| Hole pattern | To drawing or original blade | Bolt holes, slots and counterbores reproduced exactly |
| Finish options | Polished, ground or serrated | Edge protection applied to every finished blade |
Values above are our standard production range. Send the machine model, an original drawing or a photo of the blade you are replacing and we will confirm the exact specification before quoting.
Typical Applications
Pouch & Bag Making
Pouch packing machine cutter blades and sealing blades that keep pouch, sachet and bag lines running at full speed, giving a clean shear on every cycle.
