These high-performance half star & full star serrated packaging blades are precision-manufactured from premium SKD11 cold work tool steel, tailored specifically for the food packaging industry and compatible with vertical form fill seal (VFFS) packaging machines—one of the most widely used equipment in food packaging lines worldwide.
Crafted with strict heat treatment processes, the blades achieve an optimal hardness range of HRC 58-62, delivering outstanding wear resistance, impact toughness and edge retention. The dual design of half star and full star serrations provides versatile cutting capabilities: half star serrations ensure smooth, burr-free cutting for flexible food packaging materials (such as snack bags, candy wrappers and sauce pouches), while full star serrations offer enhanced gripping and cutting force for thicker or laminated food packaging films, preventing slippage during high-speed operation.
Designed to seamlessly fit VFFS packaging machines, these blades ensure precise alignment and stable performance, even under continuous high-speed production conditions. The food-grade compatible design and smooth surface finish meet strict food safety standards, avoiding contamination of food packaging materials. Each blade undergoes rigorous quality inspection for dimensional accuracy, serration precision and surface smoothness, guaranteeing perfect fit with your VFFS equipment and consistent cutting results.
Whether you are processing dry snacks, frozen food packaging, or liquid pouches, these SKD11 half star & full star serrated blades offer long service life, reduced replacement frequency and lower maintenance costs. Custom serration sizes, blade dimensions and thicknesses are available to match different VFFS machine models and specific food packaging needs.
