The rotary cutting blade is a circular hob that operates by rolling shearing. It can cut materials through in one go, delivering smooth and flat cutting sections without burrs or wire drawing. It is suitable for processes such as coil slitting, bag making cutting, and label trimming. The blade edge bears force evenly, features low wear and a longer service life. It is compatible with high-speed production lines, boasts much higher production efficiency than tearable blades, and supports a wider range of applicable materials, enabling smooth cutting of films, paper, and non-woven fabrics. However, it comes with a higher manufacturing cost, requires strict alignment precision during installation, and involves slightly complicated maintenance and debugging in the later stage. It cannot create tear marks independently and is only used for complete cutting.
Easy-tear cutting blades and rotary cutting blades may both seem to be cutting tools, yet they differ greatly in actual functions and applicable scenarios. Each has its own specialized use in daily production and cannot replace the other. Easy-tear blades belong to half-cut blades, with mostly toothed or dot-shaped cutting edges. They do not cut through materials during operation; instead, they press uniform weakening scores on materials such as films, wrapping paper and aluminum foil. They are specially used to process easy-tear openings and perforated lines, allowing users to tear open packages by hand without tools like scissors. Featuring a simple structure, such blades have low procurement and replacement costs, and their installation and debugging are also convenient. They are widely applied in processing openings for food bags, daily necessities packaging bags, express delivery bags and pharmaceutical aluminum foil sheets. However, their cutting edges bear concentrated force and wear relatively fast, requiring regular inspection and replacement to prevent problems such as untearable packages caused by overly shallow scores or damaged packages due to excessively deep scores.
Simply put, choose easy-tear blades for making easy-to-open notches and hand-tear marks. Opt for rotary cutting blades when you need to cut through materials and pursue efficient, neat cuts. Most packaging production lines use them in combination to balance the practicality of finished products and production efficiency.
