PROBLEM TO BE SOLVED: To provide a packaging film wherein the film has transparency, is free from absorption of a low molecular organic compound (fragrant component) and is excellent in tight adhesion, resistance against alkali and gas barrier property, recycling is easy and its gas barrier property or the like may not be lost even if a stretch occurs on the film. SOLUTION: A DLC film 2 is formed on at least one of surfaces of a plastic film 1, wherein the DLC film 2 comprises 75 to 55mol.% of carbon and 25 to 45mol.% of hydrogen and the DCL film 2 is formed by plasma evaporation while the film is subjected to a load of tension in its biaxial direction. |
