ply 164 as shown in fig6 in phantom outline sheet 162 is folded to provide upper panels 168 and lower panels 170 defined by common remote end margins 172 and when separated at the midpoint 174 to define spaced proximal end margins 176 and 178 respectively in the embodiment shown the upper panel 168 overlaps the attached half portion of sheet 114 indicated by numeral 136 and is transversely heat sealed to said sheet 114 by peel seal 179 as clearly shown in fig6 the seal is preferably stopped short of the upper panel proximal end margin so that a tab 180 is formed the opposed side margins 182 of the upper panel 168 and the opposed side margins 184 of the lower panel 170 are in register and are heat sealed together by peel seals 185 so that the upper panel 168 can be peeled from the lower panel 170 is to expose the outer face of the inner pouch 110 in the embodiment shown the outer face of the inner pouch lower panel 126 is transversely heat sealed to the inner face of the outer pouch lower panel 170 this seal is preferrably a weld seal 171 so that the inner pouch 110 remains attached.
