Die-cutting technology: specific requirements for die-cutting indentations in different box types

Die cutting and indentation is a critical process in the packaging and printing industry, based on the specific design requirements of the product. It involves using a combination of a die cutter and an indentation line to shape or cut the printed material or other plate blanks into the desired form under pressure. This technique is widely applied in post-printing processes and is considered a highly technical operation. Here are the detailed requirements for die-cutting processes across different types of cartons, as outlined by professionals in the field: (1) Hanging Packaging Carton This type of packaging demands high-quality die-cutting and indentation. The die lines must be smooth and precise, while the indentation lines should be strong and well-defined. The graphics and text on the surface must align perfectly with the trademark, and the position of the open skylight needs to be carefully planned. The overall design should be elegant and visually appealing. During processing, issues like cuttings or burrs at the incisions may occur. Additionally, the hanging structure must have sufficient mechanical strength to support the contents. (2) Display Packaging Carton Also known as "expandable" packaging, this type combines advertising and sales functions. Die-cutting and indentation for display boxes can be challenging due to strict size requirements. When the product is sold together with the package, the sub-carton dimensions must match the design precisely. After folding, the displayed boxes should maintain even spacing to avoid issues like product entanglement or deformation caused by excessive pressure. (3) Portable Packaging Carton These cartons are typically made from cardboard or corrugated paper and are transformed into decorative boxes after printing, die-cutting, and indentation. While they don’t require extremely high precision, attention must be paid to the handle size and the fit between parts. When the handle is not in use, it should fold flat into the box. When activated, the angle of the handle’s support should be just right to prevent cracking and ensure durability and load-bearing capacity. (4) Gift Packaging Carton Gift cartons have higher standards for die-cutting and indentation. The design must complement the product, and if there's a window, its position and shape must match the item inside. The decorative elements should enhance the visual appeal. Accuracy in size is crucial to ensure a refined and elegant final appearance. Irregularly shaped cartons require extra care during the process to avoid defects. (5) "Window-Opening" Packaging Tray This refers to a pre-designed section on the carton that is formed into a vacuum through die-cutting and indentation. The edges of the window should be clean and sharp, and the blade placement must be carefully arranged to avoid interfering with the window effect. The structural integrity of the carton after the window is cut must be maintained, and waste removal during processing should be convenient. There should be enough space between the opening and the fold lines or box edges to ensure functionality and aesthetics.
