Abstract

The present invention provides a self-standing bag with foldable flanges. The bag includes a main body, available with two corresponding side walls and a top/bottom wall connected between the top/bottom of two side walls. There are foldable flanges arranged at the top of two side walls of the main bag body, and openings are formed between two corresponding sides of the foldable flanges. The self-standing bag is positioned more reliably for an improved ads effect.
