Folding / Cup / Tray Sealing Jaws
We manufacture a specialized range of high-precision formed sealing blades, ring-shaped serrated cutters, and 3D profile packaging knives. Our products are widely used in tray sealers, cup sealing machines, blister packaging lines, and form-fill-seal automated equipment. Crafted from food-grade stainless steel (SUS420/SUS440), SKD-11, and tungsten carbide, each knife undergoes precise bending formation, CNC serration grinding, and vacuum heat treatment to guarantee high structural integrity and exceptional sharpness.
Our product lineup includes rectangular, circular, square, oval, and custom geometric frame blades tailored to your exact sealing dies, mounting hole dimensions, and film materials (PP, PE, PET, paper-plastic composites, etc.). Designed for clean and instant film cutting, our blades deliver smooth, burr-free edges that elevate overall packaging efficiency and presentation.
Key Features: High dimensional precision, razor-sharp serrated edges, clean film-shearing performance, superior corrosion & wear resistance.
Applications: Tray & container sealing machines, cup sealers, food blister packaging equipment, medical box sealing machines, and automated flexible packaging lines.
