Provided are a film usable with minimized deterioration in gas barrier properties, a molded product including the same, and a method for producing a film. According to an aspect of the invention, a film contains a gas barrier resin having a glass transition temperature of 70 °C or below and an elastomer, and has an oxygen permeability coefficient of 200 mL/(m 2 ·day·atm) or less. In a case where tension is applied to stretch the film in a machine direction (MD) at 20 °C such that a twofold increase in length of the film is kept for 30 seconds, and then the tension is released, a ratio L 2 /L 1 is 1.5 or less, where L 1 denotes the length of the film prior to application of the tension and L 2 denotes the length of the film subsequent to release of the tension. An elongation ratio at break E TD /E MD of the film is preferably 0.9 or more and 1.7 or less, where E MD denotes the elongation at break in MD and E TD denotes the elongation at break in the transverse direction (TD). A molded product according to another aspect of the present invention includes the film according to the above aspect of the present invention. |
