ABSTRACT:
A reflective film suitable for reflecting light and radio frequency energy includes a thin annealed metal foil affixed to a polymeric carrier layer or substrate wherein the polymeric carrier is thicker than the metal foil so that the foil tends to assume the physical properties, and particularly the elongation of the carrier without rupture or surface cracking of the foil upon stretching. In this manner, the polymer-metal foil laminate can be substantially deformed and stretched to fit complex shapes while maintaining a continuous, 100% reflective foil layer. The elasticity and yield strength of the substrate are selected to permit the combined foil and substrate to be stretched to fit complex shapes.
