PROBLEM TO BE SOLVED: To provide a package bag for secondary packaging in which the taking-in/out opening of a packaged article may not be opened even if an internal pressure of a standard defined by an infectious disease law becomes a pressure of 95 kPa or more, and gas and liquid of some small quantities are prevented from leaking even if a western style pressure resistance experiment is performed while a bag body is warped.SOLUTION: A package bag for secondary packaging is characterized in that, as for the package bag 1 for the secondary packaging of a primarily packaged infectious substance, a surface material 2 and a back side material comprising a plastic sheet or film and partition materials 4, 5 of a required size comprising a homogenous material on a top side comprising an opening part 15 are overlapped, respectively, and heat-sealed in a required width along an end edge serving as the top side, respectively, the surface material and the back side material are overlapped along with both partition materials, and both surface sides and a bottom surface are heat-sealed in a series except the opening part of the upper surface, and thereby formed in a bag shape. A zipper (R) is provided between both partition materials so that the partition material of the surface side and the partition material of the back side in the partition materials may not be separated by an internal pressure or deformation of a bag body.SELECTED DRAWING: Figure 1 |
