发明名称 Scrim reinforced plastic film
摘要 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.
