Abstract
A stand-up plastic food storage bag having two bottom gusset walls and a folding seam defining abutment of the front bottom gusset wall to the rear bottom gusset wall. There are gusset wall reinforced regions on an external surface of the bottom gusset walls which do not cover the folding seam, so they do not significantly interfere with folding the seam when collapsing the bag into its storage condition.
