The die-cutting and indentation process is a cutting process for the post-processing of printed matter, and is a molding process in which a printed matter is formed into a die-cutting die according to a pre-designed graphic, and the printed matter is rolled into a desired shape or indentation by a molding machine.
In the color box manufacturing process, die cutting is the most widely used postpress process. The color box of different box-type structures has different requirements for die-cutting and indentation operations. Here are some of the experiences that industry professionals have summarized.
This kind of packaging form generally has higher requirements on the quality of die-cutting indentation; the die-cutting line needs to be smooth and neat, the indentation line is required to be obvious and strong, and the graphic on the surface of the carton should be closely matched with the trademark, and the position of the opening sunroof should be reasonable, geometric The shape should be beautiful and generous, and there may be broken burrs or burrs in the incisions during die-cutting and indentation processing. In addition, the suspension should have a certain mechanical strength;
Display packaging, also known as "expanded" packaging, is a new form of packaging that combines advertising and sales. The die-cutting and indentation processing of the display packaging carton is more difficult, and the size is very strict in French. Especially when the packaged goods are sold in sets, it is required that the size of each packaging carton must meet the design requirements. When the display is unified, the gap between them should not be too large, causing the product to move in series, and it should not be too small, otherwise the carton may be deformed due to the extrusion;
3.Portable packaging carton
The carton is generally processed from cardboard or corrugated material into a decorative carton of various shapes after being printed, die-cut and indented. The portable packaging carton does not require very high precision for die cutting and indentation processing. However, it should be noted during processing that the size of the handle and the fit between the bites should be appropriate. When the handle is not activated, it can be folded flat and placed in the box; when it is activated, the support angle of each bite should be appropriate and cannot be folded. Cracks and cracks are generated to ensure that the handle has a good load-bearing strength;
This kind of carton has high requirements for die-cutting and indentation processing. Firstly, the processing form is matched with the product. Secondly, the general gift decoration carton is mostly based on the picture. If there is a window opening, the window opening position and geometry should be the same as the product. The content of the decorative painting is adapted to make it shine. The size of the carton in the die-cutting indentation process must be accurate and ensure that it is delicate and beautiful after molding. Especially when processing some irregular packaging cartons, similar problems should be paid more attention.
5."Window type" packaging carton
The so-called "windowing" is to use a die-cutting indentation to roll into a leak at a pre-designed position of the carton. When processing, the edge of the window should be smooth and clean, and the knife interface should be properly arranged. The position of the knife edge can not affect the window opening effect. Considering the strength of the carton after window opening and the ease of cleaning during processing, the window and the fold line or the box edge should have enough distance.
