YISHI manufactures high-precision Packaging Machine Knives for VFFS/HFFS, flow wrappers and tray sealing—clean cuts, long life, drop-in fit. Stock or custom from your drawing/sample, OEM-compatible.
Whether the machinery you work with has specific machine blade specifications from the original equipment manufacturers (OEM), or you need to create an industrial knife blade that is unique to your converting application, we has the custom industrial blade solutions you need.
Our serrated or toothed blades feature consistent tooth geometry, ensuring reliable tear lines on flexible packaging materials. Perfect for snacks, single-serve packs, and other food products, these blades offer superior performance in high-speed packaging lines.
Zig-zag cutoff blades are designed for decorative, easy-open cuts, ideal for pillow bags, gusseted bags, and other flexible packaging formats. These blades provide a clean and attractive opening, enhancing the user experience for products like confectionery and baked goods.
Scalloped blades offer smooth entry points that reduce film snagging on high-speed wrapping machines. These blades are essential for ensuring consistent cuts in applications where delicate films are used, such as for fresh food packaging or pharmaceutical packaging.
Our straight cutoff or guillotine blades deliver burr-free, straight cuts for pouches, lidding, and bag sealing. These precision blades ensure clean edges, ideal for applications where aesthetics and functionality are equally important, such as in medical and consumer goods packaging.
For tight-tolerance slitting of films, foils, and paper laminates, our circular slitter and score knives offer unparalleled precision. These knives are perfect for industries like packaging, printing, and converting, where accurate and clean slitting is critical to maintaining product quality.
Our punch and perforation tools are designed for micro-perforations, venting, and euro-slot punching. These tools are ideal for creating ventilation holes in packaging, such as in food packaging for moisture control or creating hanging slots for retail displays.
Center‑seal, fin‑seal, and end‑seal cutting.
Cross‑cut and longitudinal cut for confectionery and bakery.
Pillow, gusset, and quad bags with zig‑zag or straight cutoff.
Precise film cutting for MAP and lidding applications.
Slitting, perforating, and punching for tapes and laminates.
For Packaging Machine Knives used with sticky products or metallized films, a non‑stick or low‑friction coating can stabilize cut quality and reduce downtime.
