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

Die cutting and indentation is a crucial process in the production of packaging, based on the design specifications of the product. It involves using a combined die cutter and indentation tool to apply pressure, shaping or marking the printed material or plate blank into the desired form. This technique is widely used in the post-printing and packaging industry and is considered a high-technical process due to its precision and complexity. Professionals in the field have outlined specific requirements for die-cutting processes depending on the type of box: (1) Hanging Packaging Carton This type of carton requires a high level of precision in die-cutting and indentation. The die lines must be smooth and clean, while the indentations need to be accurate and strong. The graphics and text on the surface should align perfectly with the brand logo, and the skylight position must be well-placed. The overall shape should be elegant and visually appealing. During processing, care must be taken to avoid cuttings or burrs at the edges. Additionally, the hanging mechanism must provide sufficient mechanical strength to support the contents. (2) Display Packaging Carton Also known as "expandable" packaging, this type integrates advertising and sales features. The die-cutting and indentation process for display boxes is more challenging, as the dimensions are extremely strict. When items are sold together with the package, the size of the sub-cartons must match the design exactly. After folding, the display should be uniform, with minimal gaps between units to prevent misalignment or deformation caused by excessive pressure. (3) Portable Packaging Carton These cartons are typically made from cardboard or corrugated paper and are shaped 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 different sections. The handle should fold flat when not in use and maintain stability when extended. The angle of the support should be appropriate to prevent cracking and ensure durability under load. (4) Gift Packaging Carton Gift boxes demand higher standards in die-cutting and indentation. The design must complement the product, and if there’s a window, it should match the product’s shape and placement. Decorative elements should enhance the visual appeal, and the dimensions must be precise to ensure a refined finish. Irregularly shaped boxes require extra care during the process to maintain quality and aesthetics. (5) "Window-Opening" Packaging Tray This refers to a pre-designed area on the carton that is cut and indented to create a vacuum effect. During processing, the edges of the window should be clean and sharp, with the knife lines properly positioned to avoid affecting the visual impact. The structural integrity of the box after the window is opened must be maintained, and the waste removal during processing should be efficient. The distance between the window and the fold line or edge should be adequate to ensure functionality and safety.
