PROBLEM TO BE SOLVED: To provide a vacuum packaging bag for which checking of its contents can be done from outside. SOLUTION: The packaging bag (200) is formed of a laminate film (100) which is formed by laminating a plastic film (10) partly with a printed layer (11) having a transparent window portion (11a) to a transparent compound film (20) having at least a barrier layer (21) and a sealant layer (22) partly via an adhesive layer (30) while the barrier layer (21) is on the inner side. A space (202) formed on a non-laminated portion communicates with outside air. The plastic film (10) is preferably a polyester film. COPYRIGHT: (C)2004,JPO
