<p><P>PROBLEM TO BE SOLVED: To provide a packaging bag for a liquid bag which hardly generates pinholes and a liquid bag package which hardly generates pinholes on the packaging bag. <P>SOLUTION: The packaging bag 2 is hermetically sealed by heat sealing the upper edge while a two-tank medicinal solution bag 3 is accommodated in the packaging bag 2 and has a pouring plug 34 whose both sides are spot-sealed. The packaging bag 2 is formed by superposing laminated sheets 20 and by heat-sealing both side parts and the lower end part for a prescribed width. Side sealing parts SS comprise upper side edge sealing parts SSa which are formed along both side edges of the laminated sheet 20 at the upper sides and lower slanting sealing parts SSb which are slanted inside of the lower end parts of the upper side edge sealing parts SSa in a manner to support the lower end corner parts of the bag 3 to be accommodated. The laminated sheet 20 is formed by dry-laminating an outer sheet comprising a base material layer and a reinforcing layer, an intermediate sheet comprising a gas barrier layer and a reinforcing layer, and an inner sheet having a heat bondability through a release layer. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
