PROCESS FOR ENCAPSULATION OF CELLULOSE BASED SUBSTRATE USING NON-ELECTROMAGNETIC HEATING

摘要

A method for providing for encapsulating a cellulose based substrate (20) with polymeric films (43) involves heating the respective films using a non-electrogmagnetic radiation heating source and providing a pressure differential between an environment defined between the films (43) and an environment external to the films (43) so that conformance of the films to the cellulose based substrate (20) is promoted. The cellulose based substrate (20) is entirely encapsulated by the films and the films are sealed around the peripheral edges of the container as well as edges that are defined adjacent slots (32) and cutouts (42).
