A combined double-sided adhesive product and its processing method and application

Abstract

The invention provides a processing method for a combined double-sided adhesive product, the combined double-sided adhesive product comprising: a first release film (100); several double-sided adhesive units arranged on the first release film (100) (200), the double-sided adhesive unit (200) includes at least one double-sided adhesive tape (210, 220) and the second release film (230) covering the double-sided adhesive tape; covering all double-sided adhesive units (200) The protective film (400); the shape of the double-sided tape (210,220), the second release film (230) and the protective film (400) in the combined double-sided adhesive product is die-cut by a flat knife die-cutting machine made. The invention solves the problem of insufficient processing precision of the circular knife die-cutting machine for combined double-sided adhesive products, realizes the flat knife die-cutting processing of combined double-sided adhesive products, and obtains the product size tolerance of the combined double-sided adhesive products And product spacing size tolerances meet the requirements, ensuring product accuracy and quality.

Description

technical field [0001] The invention belongs to the field of processing double-sided adhesive products, and in particular relates to a combined double-sided adhesive product and its processing method and application, in particular to a method for flat-knife die-cutting combined double-sided adhesive, the prepared double-sided adhesive and its use. Background technique [0002] Die-cutting refers to the process of precision machining and cutting raw materials according to a predetermined shape to form specific parts. The double-sided adhesive is processed into a four-layer double-sided adhesive product with a protective film, a release film, a double-sided adhesive, and a shipping release film (paper) by die-cutting for the entire sheet to be pasted. In order to improve efficiency and reduce costs, double-sided adhesive products need to combine multiple double-sided adhesives for combined die-cutting. A variety of common double-sided adhesive combination adhesive products a...
