Abstract
The present invention discloses a multi-layered stretched resin film which comprises a base layer (A) containing 40 to 90 wt % of a polyolefinic resin and 10 to 60 wt % of an inorganic fine powder or an organic filler; and an amorphous resin-containing layer (B) provided on at least one side of such base layer (A), and containing 0 to 85 wt % of a polyolefinic resin and 15 to 100 wt % of an amorphous resin; where the amorphous resin-containing layer (B) has a porosity of 5% or below. Such multi-layered stretched resin film is successfully exempt from being waved or curled due to vehicle contained in offset printing ink during offset printing, and can thus ensure excellent printability.

A multi-layered stretched resin film comprising:
- a base layer (A) containing 40 to 90 wt % of a polyolefinic resin and 10 to 60 wt % of an inorganic fine powder or an organic filler;
- and
- an amorphous resin-containing layer (B) provided on at least one side of such base layer (A), and containing 0 to 85 wt % of a polyolefinic resin and 15 to 100 wt % of an amorphous resin;
- said amorphous resin-containing layer (B) having a porosity of 5% or below, and having a glass transition point of 70-140° C.
- further comprising a surface layer (C) containing 30 to 85 wt % of a polyolefinic resin and 15 to 70 wt % of an inorganic fine powder or an organic filler, said surface layer (C) being provided on at least one side of a stack which comprises said base layer (A) and said amorphous resin-containing layer (B) provided on at least one side thereof.
