Die cutting method of sticking port of packaging paper box with hidden and easily-torn port

Abstract

The invention discloses a die cutting method of a sticking port of a packaging paper box with a hidden and easily-torn port. In the invention, die cutting is carried out on the sticking port of the packaging paper box by use of the die cutting method, when a die cutting cutter board and a die cutting bottom board are laminated, a semitransparent cutter presses a bottom die exactly so as to cut through the surface of paper; the bottom die plays a role in support, so that the pressure generated by a die cutting machine during lamination can be accurately applied onto the semitransparent cutter,thus the die cutting depth is stable, the paper die cutting effect in a semitransparent area is ensured, and the paper can be prevented from secondary deformation; and the produced packaging paper box can be prevented from dislocation of located lines and paper layering phenomena when box pasting is carried out by virtue of an automatic box pasting machine,so that the product quality is effectively controlled.

Description

technical field [0001] The invention relates to the field of packaging and printing, in particular to a die-cutting method for a packaging carton with a concealed easy-tear opening. Background technique [0002] The packaging carton with concealed and easy-to-tear opening has a beautiful appearance and is widely used in the packaging of many high-end products. However, if this kind of packaging carton with a concealed and easy-to-tear opening is die-cut using an existing die-cutting process, it is difficult to ensure the stability of the quality of the die-cut product. The main problem is that during die-cutting production, it is difficult to control the die-cutting pressure at the easy-to-tear joint, and the paper at the joint joint is prone to secondary deformation during die-cutting. It causes the folder-gluer to dislocate the recognition line, so that the packaging carton cannot be completely opened after the box is glued. The complete opening rate of the packaging car...

However, if this kind of packaging carton with hidden and easy-to-tear openings is die-cut using the existing die-cutting process, it is difficult to ensure the stability of the die-cut product quality

The main problem is that during die-cutting production, it is difficult to control the die-cutting pressure at the easy-to-tear joint, and the paper at the joint joint is prone to secondary deformation during die-cutting. Causes the folder-gluer to dislocate the recognition line, so that the packaging carton cannot be completely opened after the folder-gluer

The complete opening rate of the packaging cartons with concealed and easy-to-tear openings produced by the existing die-cutting process is only about 50%-60%, which will seriously affect the production efficiency of carton packaging products
