Title:
FILM, MOLDED BODY, AND FILM MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2017/209212
Kind Code:
A1
Abstract:
Provided are: a film in which the degradation of gas barrier properties due to the use thereof can be suppressed; a molded body using the film; and a film manufacturing method. The film includes an elastomer and a gas barrier resin having a glass transition temperature of 70°C or lower, has an oxygen permeability coefficient of 200 mL/(m2·day·atm) or lower, and has an L2/L1 ratio of 1.5 or less, where L2 is the length of the film in the MD direction after the film has been elongated by an elongation factor of two via the application of tensile force in the MD direction at 20°C, maintained in the elongated state for 30 seconds, and then released, and L1 is the length of the film in the MD direction prior to applying the tensile force. It is preferable that the breaking elongation ratio, ETD/EMD be 0.9-1.7, where EMD and ETD are the breaking elongation of the film in the MD direction and the breaking elongation of the film in the TD direction, respectively. The molded body of the present invention is provided with said film.
