ABSTRACT:
A bag formed of a flaccid material for receiving and containing merchandise, the bag being formed by a sheet of such material folded along a fold line to provide two juxtaposed or overlapping generally rectangular wall panels having the side edges thereof joined together, such fold line being tucked inwardly between such overlapping wall panels to form a gusset, and a separate strip of material folded along a fold line extending along the length thereof and disposed within the gusset to extend across the entire width thereof with the fold line of the separate strip of material lying adjacent to the inwardly tucked fold of the sheet of material, the ends of the strip of material being joined to the overlapping portions of the wall panels by a heat seal extending diagonally at a forty-five degree angle across the corners thereof. The separate strip of material may be cut and formed by accessory equipment, and then inserted in the gusset by the same apparatus used to form the gusset in conventional bag forming equipment.
