1 Tri-fold side seamed plastic produce bag, method and apparatus for making same US13566491 2012-08-03 US08708879B2 2014-04-29 Greg Tan
A trifold side seamed film produce bag includes a front wall and a back wall, first and second side edges sealed together and a seamless bag bottom. 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 includes manufacturing the bags and winding them onto cores or forming the bags into coreless rolls. An apparatus for forming the side seamed bags includes an extruder, a tubing flattener, a perforator, a sealer, a corona treater, a printer and a slitter. The treated, printed bags may be stored on rolls for later slitting into two bag streams and folding into thirds.

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.

A folder system with an accordion spine 16, and a method of making same is disclosed. The folder may have a plurality of insert elements 52, 60 either at manufacture or by a stub system which are bound into the spine at the valleys 32 of the web which forms the spine. The web is made of outer zig-zag web 40, with the inner web 42, 44, 46 joining adjacent insert elements and the outer web, to create a strong spine of web and inserts.

A film bag has a pair of longitudinally extending film face panels having longitudinal edges and first and second folded film gussets having longitudinal edges welded at longitudinal seams to respective longitudinal edges of the face panels and formed with two spaced throughgoing cuts forming a handle loop. A separate film inner liner panel lies against an inner face of the first gusset, extends a full transverse width of the first gusset, and is fixed at the longitudinal welds of the first gusset to the front panels so that the liner prevents leakage from the bag through the cuts.

The plastic bag may include flexible thermoplastic sidewalls that have a pattern imparted onto them. The wrinkle pattern may be a plurality of linear ribs formed into the sidewall that may be arranged adjacent and parallel to one another. To impart the pattern to the sidewall, a thermoplastic web used to make the sidewall may be directed between a first cylindrical roller and a second cylindrical roller, each of which may have a plurality of spaced ridges extending about their peripheries. When the web is directed between the first and second rollers, the meshing of the ridges may form ribs into the web.
