Abstract:

A packaging bag material having a structure obtained by laminating of a sealant layer (1) constituted of a synthetic resin layer having an inside surface capable of heat sealing and a barrier layer (3) including a metal thin-film layer (7) with an extruded polyethylene layer (2) interposed therebetween. A synthetic resin layer (6) that is detachable from the polyethylene layer is disposed at an interface between the extruded polyethylene layer and at least one of the sealant layer and the barrier layer.
