Abstract

The present disclosure provides a flexible container. In an embodiment, the flexible container includes (A) a front panel, a rear panel, a first gusseted side panel, and a second gusseted side panel. The gusseted side panels adjoin the front panel and the rear panel along peripheral seals to form a chamber. Each peripheral seal has (i) a body seal inner edge (BSIE) with opposing ends, (ii) a top tapered seal inner edge (t-TSIE) extending from a top end of each BSIE, (iii) a neck seal inner edge (NSIE) extending from a top end of each t-TSIE, (iv) a neck arc extending between each NSIE and t-TSIE, and (v) a plane (N) extending through each neck arc. Each NSIE forms a neck angle with the plane (N), and the neck angle is from 45° to less than 90°.
