Provided is a packaging bag which is capable of preventing contamination of a packaged article by the colorant included in a laminated film and also has high mechanical strength such as impact resistance and pinhole resistance. The packaging bag is formed by configuring, into a bag form, a multilayer film formed by overlapping a plurality of laminated films in multiple layers. The colorant is included in only one of the layers excluding the layer of laminated film which comes into contact with the packaged article. The multilayer laminated film is formed in double by, for example, flattening a cylindrical laminated film. The colorant is, for example, an inorganic pigment. |
