Pouch with spout

Abstract

Provided is a spouted pouch, said pouch being suitable for achieving a high gas-barrier property. This pouch X is provided with a pouch main body 10 and a spout 20. The pouch main body 10 is configured from a film having a sealant layer on an inner surface thereof. The spout 20 is an integrally molded resin body and contains each of an olefin-based resin and an ethylene-vinyl alcohol copolymer and is attached to the pouch main body by thermal welding with the sealant layer. The sealant layer is configured from an olefin-based resin film having a heat seal strength determined by the following peel test of 10 N/15 mm or less. The peel test: two olefin-based films each lined with a fracture prevention film are partially thermal-welded by an action of a compression pressure of 0.2 MPa for 1 second at 105° C., and thereafter the thermally welded section is subjected to a peel test under the condition of a tension rate of 300 mm/min at 23±2° C.
