Abstract
Abstract An article carrying bag comprising a pigmented film and an overlying transparent film. The films are heat sealed together along adjoining side edges and each of the films are folded at one end of the bag. A heat seal is formed in the four-ply folded area at an offset position relative to the bag edge thereby providing re-enforcement whereby the bag can be efficiently suspended for display purposes. The combination of the transparent and pigmented sheets provides a viewing window and background for the most desirable display of articles included in a bag. The bags are manufactured by a method which includes the movement of overlying transparent and pigmented sheets through a folding machine whereby a narrow four-ply portion can be efficiently formed by means of a hot wire stationed so that heat will be transferred to the film for sealing the four plies of film together.

Claim 1
Independent Claim

An article carrying bag comprising a pigmented flexible film forming one wall of the bag, a transparent film of substantially the same flexible material forming the opposite bag wall, the adjoining side edges of said films being heat sealed together to form closed sides for the bag, each of said films including a short extension at one end of the bag, each extension being folded over in the same direction to provide a pair of short return portions overlying one of said films whereby four plies of said films are present at said one end, a transverse heat seal displaced inwardly from the edge of said bag at said one end and extending transversely across the bag along a line adjacent the end of said short return portions whereby the four plies of material are secured together thereby providing a re-enforced end suitable for suspending the bag while holding an article therein, the end of the bag opposite said one end remaining open during manufacturing to permit insertion of articles into the bags after formation of the heat seals, said transparent film providing a window for said bag and said pigmented film providing a background whereby said article is displayed in front of said background when held in the bag, and an opening defined by said one end of the bag to provide a means for suspending the bags during display of articles contained therein.
