Abstract
A produce bag has one side wall of a synthetic resin mesh material. The bag offers increased strength and reliability when used with automatic bag filling equipment. The mesh material forms a rear wall of the bag when a group of the bags are placed on wicket pins of the equipment for receiving produce. The front or forward wall is of a synthetic resin film. A reinforcing strip of synthetic resin film is formed along an upper portion of the mesh wall of the bag and spaced holes for wicket pin attachment are formed in the reinforcing strip. The synthetic resin film side wall has a side wall portion which extends below the mesh wall, with a lower fold being formed in the film wall to form a bottom of the bag. The synthetic resin film side also has an extension from the lower fold which is folded upwardly to join with and enclose a lower portion of the mesh side wall. The bottom portion of the bag is thus formed of synthetic resin film which yields to the impact of articles entering the bag to fill it. No seam is present between the side walls of the bag in the bottom area of the bag where it would be subject to the impact of entering articles. Top corner juncture portions of the bag are formed where the reinforcing strip, mesh wall and resin wall overlap to afford increased bag strength, as well. The bag provides greater strength, uniformity, and reliability in automatic produce packing machine operations.
