Portable packing bag made of plastic film, and method of producing the

Abstract

A portable packing bag made of plastic film for carrying flexible and/or folded products includes rectangular front and rear side panel sections which are (a) joined, one to the other, at their vertical edges to provide lateral side panel sections, (b) joined at their upper edges to provide a top cover section, and (c) initially unconnected at their lower edges to permit the bag to be filled but are thereafter joined at such edges, after filling, to form a completely closed bag. The cover section or gusset has upstanding edges that define a shallow trough at the top of the bag. The bag further includes a handle formed as a U-shaped loop which extends across the cover section and is attached to the opposite inner sides of the upstanding edges of the trough. The handle itself is formed of a pair of substantially equal sections which are joined, to form the U-shaped loop, along a seam at the apex of the loop. The bag is fabricated, in part, by placing a continuous film web on a planar work table with the intended outer surface of the bag directed upwards; applying a pair of handle strips to the film web in parallel with, and equally spaced from the center line of the film web; and joining the handle strips to the film web along parallel seams which are adjacent to the edges of the handle strips that are closest to the center line.
