A rotary die cutter is a machine used in the printing and packaging industry to cut materials into specific shapes. It operates by using a rotating cylindrical die that presses against the material, allowing for precise and efficient cutting. This method is ideal for high-volume production, as it can quickly process large sheets of paper, cardboard, or plastic. These machines are commonly used to create items like labels, boxes, and custom packaging. The rotary die cutting process is known for its speed and accuracy, making it a popular choice for manufacturers looking to streamline their production while maintaining high-quality results.
