ABSTRACT:
An enclosure having a self-supporting side wall formed of a plurality of laterally spaced ribs with non-self-supporting thin webs therebetween whereby the ribs and webs cooperate one with the other to provide an enclosure having shape-retaining characteristics. A bottom wall is provided constituting an integral extension of the side wall with the ribs being scored at the juncture of the side and bottom walls to permit the material to be folded such that the side wall and bottom wall lie generally normal one to the other. Blow molding and blown film techniques are used to form the enclosure.
