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, 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, wherein the temperature at an interface between 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.
