Abstract
A self opening bag includes front and real walls joined at their respective first and second side and bottom edges. The bag is folded at least once parallel to its side edges. At least one attaching feature is located on the outer surface of the bag adjacent the upper end and between the folded walls. The bag is releasably attached to a subsequent bag. The at least one attaching feature causes the bag to open as the bag is pulled from the subsequent bag. The once folded bag may be sealed at the bottom edges after folding to form a star-sealed bag bottom. The bags may be removably attached to each other at a perforation line and wound onto a compact roll for use with a bag dispenser. The bags may have an upper seam, a U-shaped cut and a pair of bag handles. The bags may be corona treated.
