Abstract

A continuous packing product of an absorbent article has a plurality of packing bodies are continuous with the absorbent article being packed by means of an exterior sheet and the exterior sheet has: a first resin layer which is formed of a thermoplastic resin, and a second resin layer which is formed of a thermoplastic resin with a melting point higher than that of the thermoplastic resin forming the first resin layer. A bonded region configured to partition the packing unit by means of thermal bonding is formed on the exterior sheet. The second resin layer is laminated on the first resin layer in at least the bonded region and the thermoplastic resin configuring the second resin layer is soluble in a solvent.
