A die-cut product and its processing technology that can solve the problem of anti-release

Abstract

The invention provides a reverse releasing preventing die cut product and a machining process thereof. The bottom of the reverse releasing preventing die cut product is provided with a bright semi-finished product for bearing the reverse releasing preventing die cut product, the bridge semi-finished product comprises a bottom paper, which is provided with a plurality of bar-shaped pad units side by side in the extending direction, the top surfaces of the cushion units are adhered to a part of the bottom surface of the extending part of a protective membrane, and the cushion units form a gap between the bottom surface of an adhesive membrane and the top surface of the bottom paper; the reverse releasing preventing die cut product comprises the adhesive membrane and the protective membrane adhered to the top surface of the adhesive membrane, a reverse adhesive membrane is arranged between the adhesive membrane and the protective membrane and at the start position from which the protective membrane can be released, the extending area of the reverse adhesive membrane is smaller than that of the adhesive membrane, and the releasing force between the reverse adhesive membrane and the adhesive membrane is smaller than that between the reverse adhesive membrane and the protective membrane. By means of the reverse adhesive membrane and the cushion units, the reverse releasing preventingdie cut product can completely avoid the problem of reverse releasing.

Description

technical field [0001] The invention belongs to the technical field of die-cutting, and in particular relates to a die-cutting product capable of solving the problem of anti-release and a processing technology thereof. 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; if the protective film is slightly heavy, it will cause the film to be taken away when...

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, there is a problem of anti-release; the protective film is slightly heavy, which will cause the film to be taken away when the die-cut product is assembled and the protective film is peeled off, that is, the peel-off material is reversed.

[0003] Foam material is more and more used in the current die-cutting industry. It has the characteristics of loose surface material and low density. However, the foam has strict requirements on the selection of protective film. If the protective film is too heavy, the foam will be torn. , and the lighter side will have the problem of leaving the bottom paper of the product. So far, no suitable protective film has been found to match this type of foam, so the die-cutting production process causes a great waste of raw materials

At present, 90% of the problems of die-cut products using foam are anti-release problems, which are also the most complained about by customers, and anti-release problems are also the "cancer" of this type of products, which are difficult to completely eradicate

However, the raw material value of die-cut products is relatively high, which accounts for a large proportion of the total cost of the product. Due to the existence of the anti-release problem, customer satisfaction is reduced, and the market competitiveness of die-cut products is seriously reduced.
