ABSTRACT:
A composite endless form for making flexible, windowed, form, fill and seal bags includes an endless strip of flexible, substantially opaque, paper-like material having a print side thereon with printed indicia thereon and an adhesive side, opposite the print side, with an adhesive thereon. The endless strip of paper-like material includes individual bag forms attached side-to-side thereon, each to be used for making a windowed bag, the endless-strip of paper-like material having a window opening cut in each individual bag form. The window openings are oblong and extend diagonal to a direction of elongation of the composite endless form. A heat-sealable film is adhered to the endless-strip of paper-like material on the adhesive side thereof to cover substantially all of the adhesive side. The composite endless form is placed in a roll to be fed to form, fill and seal machines for making windowed bags.
