Stack of bags each having congruent cutouts and perforated lines

A stack of bags comprising:

• rectangular sections of synthetic thermoplastic film joined together at bottom fold lines and forming front and rear walls of each bag,
• seam welds at each lateral side of each bag,
• an open end provided in each bag opposite its bottom fold line,
• perforation lines, provided in said rear wall of each bag, defining two upper, laterally disposed corner portions of said rear wall of each bag of approximately single quadrant shape,
• cutouts provided in said front wall only of each bag defining an approximately single quadrant-shaped cutout portion in each of two upper, laterally disposed corner portions of said front wall,
• said cutouts being substantially congruent, parallel to and radially offset corresponding to said perforation lines of each bag,
• each bag further including hanger holes in said upper, laterally disposed corner portions thereof aligned with hanger holes in the other bags in said stack of bags,
• said perforation lines of each bag having relatively long lands adjacent to an opening-defining edge of said rear wall and adjacent each said lateral side of each bag and relatively short lands in an intermediate portion located between said relatively long lands, and
• each bag including grip holes located adjacent its open end and centrally between said two upper, laterally disposed corner portions of said rear wall and said cutouts of said front wall.
