Linear polyethylene film and process for producing the same
 Disclosed herein is a monoaxially or biaxially stretched film comprising principally of a linear polyethylene and capable of reduction of thickness to a greater extent than possible with the conventional films of this type. The film according to the present invention, though incomparably small in thickness, has excellent impact strength, stiffness, tensile strength and tear strength and can be favorably utilized as a film for packaging bags used for packaging relatively heavy commodities.
