Abstract:
A method for counteracting the curling tendency of a gas barrier film having a tendency to curl up with a support side thereof facing inside, comprising (1) heating the gas barrier film from the support side thereof to thereby control the support temperature to fall between Tg and Tg+40° C., and (2) conveying the film in the roller circumferential direction within one second after the temperature of the support has reached Tg, while a part of the gas barrier layer of the gas barrier film is kept in contact with a film surface center part noncontact roller wherein Tg means the glass transition temperature of the support.
