A disposable bag (10) capable of being mounted to a support structure, the bag having a first open end (15) and a second closed end (19), the bag first end being smaller in relative dimension than the bag second end, the bag comprising a first containment portion (12) and a second elastic portion (14), the bag first containment portion is a thermoplastic polymer, preferably of a polyethylene polymer, the bag second elastic portion is a thermoplastic rubber, and optionally a tackifier, the bag first and second portions are a coextruded, coextensive film. Another aspect of the invention is a method of fabricating a disposable bag capable of being mounted to a support structure, including simultaneously feeding said first and second polymer feed stocks into an extrusion device; extruding a polymer film from the device wherein said polymer film has a first portion comprising said first polymer feed stock and a second portion comprising said second polymer feed stock; and fabricating a disposable bag from said polymer film.
