Abstract
A laminate film having two olefin type films, a heat resistant film with a vapor deposition coat of aluminum oxide on each surface thereof and a heat adhesion resin layer for joining the olefin type films to the heat resistant film. Instead of the heat resistant film and the heat adhesion resin layer, an oriented film of ethylene-vinyl alcohol copolymer resin layer and a co-extrusion resin layer including a heat adhesion resin layer and an olefin type resin layer may be used. The heat adhesion resin layer is maintained in a heating state for a predetermined time when the laminate film is manufactured.
