Serrated blades for packaging machines: bag sealing, pillow flow wrap, vertical form-fill-seal and automatic cutting stations. Tooth profile is the whole job — a long serrated knife for a wide seal bar, a fine zig-zag serrated knife for thin film, a coarse straight tooth for heavy laminate. We grind tooth pitch, depth and land width to the film you run, so the blade cuts the web without shattering the seal.

Coating matters as much as the tooth: a titanium coated serrated blade resists the adhesive build-up that pulls a hot seal apart, and a PTFE coated heat sealing blade runs cleaner still on aggressive laminates. Length, hole spacing and thickness follow your sealing jaw or a worn sample. Tell us the film structure and the seal width and we will match the tooth and the coating.
