Abstract
A multi-layered stretched resin film comprises a base layer (A) comprising more than 90 wt % of a polyolefinic resin and less than 10 wt % of an inorganic fine powder and/or an organic filler; and an amorphous resin-containing layer (B), comprising 0 to 85 wt % of a second polyolefinic resin, which may be the same or different than the first polyolefinic resin, and 15 to 100 wt % of an amorphous resin. The amorphous resin-containing layer (B) is disposed on at least one side of the base layer (A), and has a porosity of 5% or less. Such multi-layered stretched resin films are resistant to waving or curling caused by exposure to the vehicle component of offset printing inks during offset printing, and therefore have excellent printing properties.
