The gusseted side panels adjoin the front panel and the rear panel along peripheral seals to form a chamber. (B) Each peripheral seal has (i) a body seal inner edge (BSIE) with a bottom end and an opposing top end, (ii) a bottom tapered seal inner edge (b-TSIE) extending from the BSIE bottom end, and (iii) a top tapered seal inner edge (t-TSIE) extending from the BSIE top end. (C) The t-TSIE has a length that is at least 1.1 times greater than the length of the BSIE (in mm).
