Abstract: The present invention improves performance of the side and/or fin seals of plastic bags through the use of resins that have a narrow molecular weight distribution or polydispersity. The performance of the side seal and/or fin seal of a plastic bag is improved by using body panels which comprise a first resin, and optionally, a second resin. The first resin is preferably prepared in the presence of a single site catalyst. The first resin has a polydispersity of from about 1 to about 4, a melt index of from about 0.2 to about 20, and a melt flow ratio (I.sub.20 /I.sub.2) of from about 12 to about 35. The use of such first resins results in side and fin seals which are stronger, tougher, and less likely to leak. The second resin is a polymer such as LDPE, LLDPE, or a blend thereof In body panels comprising both a first and a second resin, the first resin may be coextruded with LDPE or LLDPE as a thin layer of the body panel or the first resin may be blended with the LDPE and/or LLDPE.

Abstract: A system for suspending a pack of thermoplastic bags, loading bags, removing loaded bags and for automatically opening the next bag preparatory to loading it by having a pack of handled bags suspended from laterally spaced elongated rods of a rack. The bags have been corona discharge treated to such an extent that the application of pressure will cause adjacently facing regions to releasably adhere together until a moderate force separates them. During removal of a bag front the bag pack at least a portion of the front wall of the next bag will follow the bag being removed for a short distance before separation thereby opening said next bag rendering it ready for loading. An improved means for applying the requisite pressure is disclosed herein.

Abstract: A reclosable standup bag and a method for manufacturing the bag. The bag includes opposing top and bottom panel assemblies. The top panel assembly includes first and second opposing fins having upper edge portions that define a mouth opening. Opposing front and back wall panels extend between the top and bottom panel assemblies. First and second opposing gusseted side wall panels couple and bridge the side edges of the front and back wall panels, defining four wall corners. A resealable closing assembly is coupled to the upper edge portion of the fins. The method for manufacturing the bag includes providing a lay flat web of a flexible packaging material and cutting comer reliefs at the location of the upper side corners of the bag. The lay flat web is run over a forming tube to create a duct-shaped cylinder with overlapping side edges. The side edges are joined and are fin sealed to form a tube having a bottom opening and a top opening.
