ABSTRACT:
A four corner bag especially suitable for packaging dry cereal, and method of making the bag from sheet or plastic film material. The bag is provided with opposite wall panels joined at a closed bag bottom and closed opposite sides, the panels defining an openable bag top provided with a reclosable fastener along the inner ends of upstanding pull flanges. Lower corner chamfer seals extend from the closed bottom to the sides of the bag. Upper corner chamfer seals extend from adjacent to the ends of the reclosable fastener to the top edges of the pull flanges. Thereby, when the bag is filled, the chamfer seals will free the four corners of the bag from interfering with easy reception and packing of the filled bag in a fairly close fitting carton.
