Problems solved by technology

However, the existing decorative films are generally printed on the surface after hot stamping, resulting in insufficient three-dimensional patterns, dull and dull, and low aesthetics. After being combined on the surface of the product through the IML process, the overall visual effect of the product is poor. , at the same time, the existing decorative films also have poor mechanical properties and are prone to damage during use

Abstract

The invention discloses an IML film and a preparation method thereof. The IML film comprises a carrier layer, the carrier layer comprises a first surface and a second surface, a laser mold pressing layer and an electroplated layer are sequentially arranged on the first surface, and a printing layer is arranged on the electroplated layer or the second surface. The IML film has a better visual effect and can play a better decorative role.

Description

technical field [0001] The invention belongs to the field of membrane technology, and in particular relates to an IML membrane and a preparation method thereof. Background technique [0002] In order to improve the aesthetics of existing electronic products, such as mobile phones and tablet computers, the surface of electronic products is usually covered with a layer of decorative film during production, and the surface of existing various mobile phone cases is also covered with a layer of decorative film. To meet the aesthetic needs of different consumers, when this type of decorative film is combined with the product, the IML process (in-mold insert injection molding) is mostly used, that is, the decorative film is cut into a suitable size and put into the mold, and then injected into the mold After molding and demoulding, the decorative film is combined on the surface of the product. However, the existing decorative films are generally printed on the surface after hot st...
