A pot belly bag which includes a bag portion having four walls and a top portion, and a floor portion; a portion extending outwardly and downwardly from the floor portion, which defines the pot belly portion; a pair of channels formed along either sidewall of the pot belly portion with the channel sleeves secured along the underside of the pot belly portion of the bag which results in the two sleeves and the pot belly functioning as a united unit to overcome various stresses normally placed upon the bag. The bag also provides a free flowing product which may attempt to push the sidewalls of the pot belly outward contacts the plastic channels in an attempt to outwardly displace the channel, but as the channel begins to move outwardly it immediately encounters the outer sleeve which is tied to the pot belly which restricts outer movement and spreads the forces out along its entire length.
