This serrated packaging knife is a core cutting component for pouch‑making machines. Its long serrated edge is designed for continuous pouch cutting, severing plastic film, composite film and paper packaging substrates. With precise tooth‑profile grinding and complete heat treatment, the blade delivers sharp, evenly‑spaced teeth for fast cutting at high speed. It reduces film stringing, pouch tearing and burr defects. Custom options fit various line speeds and materials to improve pouch cut‑edge quality.
