A self-opening style bag formed of a tube with a bottom constructed of folded-inward-portions of side walls and overlying portions of front and rear walls, all folded around a perimeter fold line. The tube provides adhesive strips on portions of the bottom region of the tube to assemble the bottom of the bag wherein at least the front wall and rear wall have transverse adhesive strips applied adjacent the fold line and edge strips along edges in the bottom region. The side walls have adhesive applied along bottom edges thereof. Alternately a heat sealable material is applied over an inside surface of the bag and local heating is used to effect seals. When the side walls are folded inward, they are sealed at all seams in the bottom of the bag to prevent small articles from becoming trapped between seams.
