Abstract

The invention relates to a decorating film which comprises a first film layer and a second film layer, and a soft tactile layer is arranged between the first film layer and the second film layer. A shell comprises an outer layer and a matrix layer combined on the outer layer, the outer layer comprises a first film layer and a second film layer, and a soft tactile layer is arranged between the first film layer and the second film layer. A manufacturing method of the shell comprises the following steps: providing a first film layer, a second film layer and a soft tactile layer; providing two relatively rotated rollers, and forming a slit between the two rollers; leading the two rollers to relatively rotate, leading the first film layer, the second film layer and the soft tactile layer to mutually bond to penetrate through the slit between the two rollers, and rolling the first film layer, the soft tactile layer and the second film layer into a whole; and combining a matrix layer on the surface of the second film layer.

Description

technical field [0001] The invention relates to a decorative film, a casing using the decorative film and a manufacturing method of the casing. Background technique [0002] The shells of existing portable electronic products are mostly made by IML (in-mold film injection molding) process. The casing made by this process usually includes a transparent plastic film, a trademark or pattern formed on the surface of the plastic film, and a plastic base layer injection-molded on the film and the trademark or pattern. The film needs to have a certain hardness to ensure the implementation of the subsequent hot-press forming process and to make the film have better wear resistance. At present, in order to make the appearance surface of the film have a soft touch, it is common practice to spray a leather paint layer with a soft touch on the appearance surface of the film. Since the leather paint layer is arranged on the appearance surface of the film, and the leather paint layer do...
