PROBLEM TO BE SOLVED: To provide a non-styrene resin film having a gas permeability that is excellent in a balance of properties such as rubber elasticity, gas permeability or the like and that is excellent in environmental adaptability and economical efficiency. SOLUTION: The non-styrene resin film having a gas permeability is a monolayer film or a multilayer film comprising a non-styrene resin composition wherein the resin film has an elongation set of not more than 50%, a permeability of water vapor of 9-50 g/m<SP>2</SP>24 h, a permeability of oxygen gas of 600-15,000 nmol/m<SP>2</SP>s 100 kPa and a permeability of carbonic acid gas of not less than 2,000 nmol/m<SP>2</SP>s 100 kPa.
