Abstract: A radiant energy device for shrinking a thin film onto an open top of a container, the radiant energy device comprising: a source of power, to provide power to the radiant energy device; a plurality of fixed energy-emitting units, each of the units when energized being configured to emit radiant energy towards the shrinking film on said open top of the container; and a switching means, operatively connected between the source of power and each of the energy-emitting units, to independently activate at least two groups of the energy-emitting units; wherein, a first group of the energy-emitting units partially shrinks the thin film onto the container, and a second group finishes the shrinking.
