ABSTRACT:
Process for forming a scrim-reinforced film wherein a molten, film-forming plastic, such as polyethylene, in a high state of fluidity is fed onto an unsupported scrim and solidified by cooling to produce a scrim at least substantially completely enclosed and surrounded by the plastic. The film, thus produced, can be formed into a high strength bag container by a folding and cutting operation utilizing hot knife means capable of fusing and thus sealing the plastic. In a preferred embodiment, the plastic is extruded onto the scrim and is subsequently heat shrunk to cause the scrim fibers to buckle and give the appearance and feel as well as the strength of a reinforced material.
