A kind of bridging semi-finished product and its technology for solving the problem of leaving bottom paper

Abstract

The invention provides a bridged semi-finished product for solving backing paper poorness and a technology thereof. The bridged semi-finished product is used for bearing a die-cut product; the die-cutproduct comprises an adhesive film and a protective film adhered to the top surface of the film; the protective film stretches out for a distance from one end of the adhesive film to form a stretchedpart of the protective film; the bridged semi-finished product comprises backing paper arranged at the bottom; a plurality of strip-shaped heightened parts are arranged side by side along the stretching direction of the backing paper; the top surfaces of the heightened parts are adhered to a part of the bottom surface of the stretched part of the protective film; through the heightened parts, a gap is formed between the bottom surface of the adhesive film and the top surface of the backing paper; a part, which is not adhered to the top surfaces of the heightened parts, of the bottom surface of the stretched part of the protective film is a force applying position when the die-cut product is taken down. A certain gap is formed between the backing paper of the bridged semi-finished productand an adhesive surface of a product so as to prevent the backing paper problem due to direct contact of the product and the backing paper, so that the backing paper poorness is fundamentally solved.

Description

technical field [0001] The invention belongs to the technical field of die-cutting, and in particular relates to a bridging semi-finished product and a bridging process for solving the problem of leaving a bottom paper. Background technique [0002] 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 if it is too light, there will be a 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 by customers. Anti-release problems are also the "cancer" of this type of products...

AI Technical Summary

Problems solved by technology

[0003] The present invention aims at the anti-release problem of die-cut products using foam in the prior art, and provides a bridging semi-finished product and bridging process for solving the problem of leaving a bottom paper. With the help of this process, the bottom paper and There is a certain gap on the rubber surface of the product to prevent the problem of the backing paper from direct contact between the product and the backing paper, and fundamentally solve the problem of the backing paper
