PROBLEM TO BE SOLVED: To provide a gas collection bag of gas manufactured in stable quality. SOLUTION: This gas collection bag has a bung hole for injecting and/or discharging sampled gas. The bag body of the collection bag is formed by heat-sealing a laminated body 3 made of only polyester resin where a substrate film 1 made of polyester resin and a sealant 2 made of polyester resin are stacked. Preferably, the laminated body 3 is formed by extrusion-laminating the sealant 2 made of polyester resin on a biaxial stretching polyethylene terephthalate film without interposing an anchor agent layer. Preferably, the polyester resin of the sealant 2 is isophthalic acid modified polyethylene terephthalate. COPYRIGHT: (C)2009,JPO&INPIT
