Process for encapsulation of cellulose based substrates using adhesive

摘要

A method for encapsulating a cellulose based substrate with polymeric film involves applying an adhesive to at least one of the respective films 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 substrate is promoted. The cellulose based substrate is encapsulated by the polymeric 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.
