Summary:PROBLEM TO BE SOLVED: To solve the problem of deterioration in stiffness of a composite film as a whole when reducing the thickness of sealant as a method for reducing resin usage in a packaging bag, and also solve the difficulty in using foamed sealant as another method to reduce the resin usage due to a deterioration in barrier property when the foamed sealant is singly used.SOLUTION: In a packaging bag using a laminated film comprising at least a sealant layer and a barrier layer, the sealant layer includes a foamed layer, and the barrier layer is transparent.
