Reverse-pasting-film-type die-cutting product and processing technology thereof

Abstract

The invention provides a reverse-pasting-film-type die-cutting product and a processing technology thereof in allusion to a condition that a belt stripping reverse release problem is easily caused while a protecting film in a die-cutting product is slightly heavy. The die-cutting product comprises a pasting film and the protecting film pasted on the top face of the pasting film. A reverse pastingfilm is installed between the pasting film and the protecting film. The reverse pasting film is installed in an initial position of stripping the protecting film. An extending area of the reverse pasting film is smaller than an extending area of the pasting film, and a stripping force between the reverse pasting film and the pasting film is smaller than a stripping force between the reverse pasting film and the protecting film. The reverse-pasting-film-type die-cutting product is capable of, through additionally installing the reverse pasting film in the die-cutting product, and verified by anexperiment, completely avoiding the belt stripping reverse release problem from occurring.

Description

technical field [0001] The invention belongs to the technical field of die-cutting, and in particular relates to a reverse-film die-cutting product and its processing technology. Background technique [0002] In the die-cutting industry, there are many die-cut products that need to choose a suitable protective film, but the weight fluctuation of the existing protective film is as high as 3gf / mm. Moreover, the fluctuation range of the weight of the existing protective film has encountered a bottleneck in the industry and cannot be reduced for the time being. As a result, when selecting a protective film for single-sided adhesive die-cut products, when the protective film is slightly lighter, the peeling force is too small, which will cause the protective film to be clamped Sometimes there is a problem of sticking the film and leaving the bottom paper; the protective film is slightly heavy and the peeling force is too large, which will cause the film to be taken away when the ...

Problems solved by technology

[0002] In the die-cutting industry, there are many die-cut products that need to choose a suitable protective film, but the weight fluctuation of the existing protective film is as high as 3gf / mm.

Moreover, the fluctuation range of the weight of the existing protective film has encountered a bottleneck in the industry and cannot be reduced for the time being. As a result, when selecting a protective film for single-sided adhesive die-cut products, when the protective film is slightly lighter, the peeling force is too small, which will cause the protective film to be clamped When the film sticks to the backing paper, the problem occurs; the protective film is slightly heavy, and the peeling force is too large, which will cause the film to be taken away when the die-cut product is assembled and peeled off the protective film, that is, the peeling material reverses.

However, due to the existence of the anti-release problem, customer satisfaction is reduced, and the market competitiveness of die-cut products is seriously reduced.
