ABSTRACT:
A trifold side seamed plastic produce bag includes a front wall and a taller back wall, first and second side edges sealed together and a seamless bag bottom. The taller back wall provides means for finding the bag opening. The bag is joined at the side edges to additional bags by a perforation. The bag is corona treated on at least one wall and promotional material is printed on the treated surface. The bags are folded to one third of their height to fit compact bag roll dispensers. The bags are folded in a Z-fold or C-fold configuration. The method and apparatus for producing the bags includes a slitter that removes a strip of plastic from only the top layer of the bag stream to form an extended flap on each bag. The method includes manufacturing the bags and winding them onto cores or forming the bags into coreless rolls.
