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 cylinder with sharp edges, known as a die, which presses against the material as it moves through the machine. This process allows for high-speed production and precise cuts, making it ideal for large-scale manufacturing. These machines can cut various materials, including paper, cardboard, and plastic. Rotary die cutters are often used to create items like labels, boxes, and custom packaging. Their efficiency and accuracy make them a popular choice for businesses looking to streamline their production processes.
