Abstract
A method for encapsulating a cellulose based substrate with polymeric film involves raising the temperature of the respective films using an electromagnetic radiation source and providing a pressure differential between an environment defined between the films and an environment external to the films so that conformance of the films to the cellulose based substrates is promoted. The cellulose based substrate is entirely encapsulated by the plastic films and the films are sealed around the peripheral edges of the cellulose based substrate as well as edges that are defined by slots and cutouts.
