초록 ▼

A flat bottom plastic bag of two sided panel construction with the bottom of the bag formed by a gussett extending between the sealed ends of the bag, at which point the bag side panels are joined together, with the bag bottom gusset having a central fold line that is, in the flattened relation of the bag, disposed between the lower portions of the bag side panels, and that in such relation forms a first pair of adjacent bag plies that includes one of said bag side panel lower portions, and a second pair of bag plies that includes the lower portion of the other bag side panel, with said respective sets of bag plies being respectively joined together but free of adherence to each other by diagonally extending heat seals on either side of the bag that extend diagonally from the bag respective ends in converging relation to adjacent the respective bottom edgers of the bag that are defined by the respective bag plies. The bag has its ends formed by heat sealing the two bag side panels together at the bag ends along lines extending normally of the bag bottom, with the bag side panels also being severed across the top of same to both define the bag open end and a curved handle type open top of the bag. Also disclosed is a method of making a plurality of such bags from flattened plastic film tube stock, with no waste of the film material of the stock, and with the bags to be formed extending transversely of the tube stock.
