Conformable reflective film

Abstract

The present disclosure includes a stretchable reflective film comprising a transparent polymer layer; a continuous metal layer comprising at least one of tin or indium; a non-reactive adhesive layer;and a stretchable film layer. The stretchable reflective film has at least 30% specular reflectivity when stretched by 50% of the unstretched length according to Specular Reflectivity Test Method.

Description

Background technique [0001] Colored and graphic films are used in a variety of applications, including for wrapping surfaces of personal or commercial vehicles, buildings, and other interior and exterior surfaces. When applied to vehicles, graphic films can provide a cost-effective alternative to vehicle repainting. Additionally, the graphic film can often be removed, allowing for a more temporary color change when compared to paint. [0002] Metallized films are a popular class of graphic films. Specifically, metallized films can provide a decorative look or specular reflection that is simpler and more cost-effective than traditional chrome plating. However, it is very challenging to fabricate conformable metallized reflective films such that they stretch into the shape of a three-dimensional surface, are visually uniform and reflective, and remain in place when applied in deep channels or around sharp radii . Stretching metallized reflective films with or without heat ca...
