Abstract
In one aspect the present invention relates to a method of making an encapsulated electrically energized device, the method comprising: providing a first layer and a second layer each independently comprising a copolyester, a polycarbonate, a polyacrylate, polycarbonate/polyester miscible blends, or mixtures thereof, providing the electrically energized between the first and second layer, thermocompressively fusing the first layer and the second layer to encapsulate the electrically energized device by applying pressure at a temperature, sufficient to form the article, to a perimeter of the surface of the first and second layers, wherein the perimeter does not overlap the electrically energized device, wherein the temperature at the interface of the first and second layers is equal to or greater than Tg of the first layer and the second layer, and wherein the polyester layers have a flow during encapsulation less than the flow that induces fractures in the electrically energized device.
