摘要: A method for encapsulating a cellulose based substrate (20) with polymeric film (43) involves raising the temperature of respective films using an electromagnetic radiation source and providing pressure differential between environment defined external to so that conformance substrates is promoted. The entirely encapsulated by plastic are sealed around peripheral edges as well slots (32) cutouts (42).
