A large plastic lawn or trash bag is provided including a tubular hem extending about its open end. An access opening is formed at one point about the hem opening thereinto and a plurality of pairs of registered openings are formed through the bag and the material defining the free marginal edge of the hem along the path the free marginal portion of the hem is secured to the bag. An elongated stiff but flexive reinforcing strip is provided of a length somewhat greater than the length of the periphery of the open end of the bag and the opposite ends of the strip are provided with coacting structure by which the opposite ends may be secured together in adjusted overlapped relation. The reinforcing strip may be inserted into the hem through the access openings thereof and have its opposite ends releasably secured together with the reinforcing strip serving to maintain the open end of the bag open or, alternatively, the strip may be threaded through the registered openings and thereafter have its ends removably secured together so as to function as a reinforcement strip to maintain the open end of the bag open. The reinforcing strip is arcuate in transverse cross section in order to increase the stiffness thereof when functioning as a reinforcing strip, but the arcuate strip is only appoximately 30 degrees in angular extent to enable the strip to be coiled into a coil of a diameter no more than one-tenth the length of the reinforcing strip to thereby enable the strip to be readily packaged within a package containing a plurality of folded bags with which the strip ultimately is to be used.

In combination, a flexible plastic bag including a first closed end and a second open end, said bag, at said second end, defining a terminal end band extending about said second end and a peripheral band extending thereabout closely spaced from said terminal end band toward said closed end, said open end including a reversely turned portion intermediate said bands with the latter disposed in registered superposed relation, said bands being bonded together along a path disposed intermediate the free edge of said terminal end band and said reversely turned portion to define a tubular hem extending about said open end intermediate said path and said reversely turned portion, said bands having pairs of registered openings formed therein spaced about said open end, an elongated, stiff, but flexive reinforcing strip including joining means at its opposite ends releasably securing said ends together against longitudinal shifting relative to each other, said strip being lengthwise threaded through adjacent pairs of registered openings, said strip, when threaded through said registered openings and having said opposite ends secured together serving to reinforce said one end of said bag against collapse, said strip being generally arcuate in transverse cross section with its major radius of curvature side thereof disposed outermost.
