Abstract
A method and an apparatus for the production of a composite plastic material consisting of oriented polymer filaments and a polymer film web, and more particularly, the production of a composite material which possesses an improved physical strength and higher tear resistance in comparison with plastic film materials which are not reinforced. An extrusion die is used for example, a conventional tubular extrusion die for extruding a continuous blown tubular plastic film web and wherein the die orifice is encompassed by spinerette apertures through which there are concurrently extruded a plurality of polymer filaments which are oriented and initially conveyed along a path substantially parallel to but not in adherence with the blown tubular plastic film web. Upon a further separation of the filaments and the tubular film, the filaments may be at least partially coated with a suitable adhesive material and, thereafter, adhesively bonded or laminated to the surface of the film web in order to produce a composite material constituted of filaments and film.
