Selecting the ideal machine depends on the box type (corrugated, rigid, or folding cartons) and your target output volume. For high-speed industrial production, fully automatic lines are essential to minimize labor costs, while semi-automatic machines offer flexibility for custom, small-batch gift boxes. Key technical factors include the maximum and minimum folding sizes, paper thickness compatibility (GSM range), and the precision of the positioning system (look for CCD image sensor positioning for high-end rigid boxes).
