Heavy-duty quad seal plastic bag with side handle holes

Abstract

A heavy-duty plastic bag is comprised of a flat front panel, a back panel and gusseted longitudinal side panels. One of the gusseted longitudinal side panels has extended opposed gusseted side walls to form bag carrying end panels. The bag carrying end panels are sealed with one another and are each provided with three spaced-apart handle holes for ease of carrying the bag by one or both ends of a person with the bag disposed horizontally to facilitate manipulation in carrying of the bag. The bag carrying end panels provide for reinforced hand holes and comfort to the hands of a user person. The gusseted side panels and front and back panels provide a heavy-duty plastic bag with four display panels.

1 . A heavy duty plastic bag comprising a flat front panel, a flat back panel and gusseted longitudinal side panels, said bag having a top end and a bottom end adapted to be sealed for containing a product in said bag, said gusseted longitudinal side panels each having opposed gusseted side walls collapsible against one another on a side central fold line, one of said longitudinal side panels having extended opposed gusseted side walls to form bag carrying end panels, and seal means to secure said bag carrying end panels with one another, three spaced-apart handle holes formed in said bag carrying end panels with said handle holes of each bag carrying panel aligned with one another, one of said handle holes being disposed substantially at mid-length of said bag carrying end panels to constitute a central hand hole, the other two of said handle holes being substantially equidistantly space don opposed sides of said central hand hole, said hand holes permitting said heavy duty bag to be carried forms aid gusseted longitudinal side panel by the use of one or both hands of a person disposed through said hand holes with said bag extending horizontally. 
     
     
         2 . A heavy-duty plastic bag as claimed in  claim 1  wherein the other of said opposed gusseted side panel which is not provided with bag carrying end panels has an end sealed strip formed with a longitudinal side end edge section of a respective one of said front and back panels to form a reinforced gusseted longitudinal side panel, said sealed bag carrying end panels also reinforcing said one of said longitudinal side panels. 
     
     
         3 . A heavy-duty plastic bag as claimed in  claim 2  wherein said self means is a heat seal to secure said bag carrying end panels with one another at least in a surrounding area of said three hand holes. 
     
     
         4 . A heavy-duty plastic bag as claimed in  claim 2  wherein each said bag carrying end panel comprises two plies of multi-layer plastic films, one ply constituted by a longitudinal side end section of one of said front and back panels, and the other ply formed by said one of said extended opposed gusseted side walls, said two plies being heat sealed to one another along their entire length. 
     
     
         5 . A heavy-duty plastic bag as claimed in  claim 1  wherein said front and back panels and said gusseted longitudinal side panels form four distinct display panels for containing printed matter, said gusseted side walls being visible when said heavy-duty plastic bag is resting flat on said front or back panel or when stacked flat on one another whereby to display said printed matter. 
     
     
         6 . A heavy-duty plastic bag as claimed in  claim 1  wherein one of said front and back panels is provided with a re-sealable opening formed adjacent one of said top and bottom ends thereof for access to a product contained in said heavy-duty bag. 
     
     
         7 . A heavy-duty plastic bag as claimed in  claim 4  wherein said opposed bag carrying end panels when folded against one another provides four plies of said multi-layer film to form reinforced hand holes for carrying a heavy content and provide comfort to the hands of the person carrying said heavy-duty plastic bag. 
     
     
         8 . A heavy-duty plastic bag as claimed in  claim 1  wherein said extended opposed gusseted side walls have a reinforcing plastic film sheet patch disposed longitudinally between an inner surface of said opposed gusseted side walls and a respective one of a longitudinal side end edge section of said front and back panels and secured thereto by said seal mean, said opposed bag carrying end panels, when folded against one another, provide six plies of plastic film material to form reinforced bag carrying end panels. 
     
     
         9 . A heavy-duty plastic bag as claimed in  claim 1  wherein said opposed gusseted side walls of said opposed gusseted panels are provided with a tack seal hole adjacent an end thereof, said tack seal holes of said opposed gusseted side walls being juxtaposed when said opposed gusseted side walls are collapsed on one another, said holes exposing a back surface of said back and front panels for heat welding said opposed back surfaces to one another in the area of said tack seal holes. 
     
     
         10 . A heavy-duty plastic bag as claimed in  claim 1  wherein said heavy-duty plastic bag is formed from 48 gauge multi-resin polyester material.
