An extruded multilayer film includes a top layer comprising a blend of a polyolefin and adsorbent silica. The adsorbent silica is 5% or more of the blend and the polyolefin is 95% or less of the blend. The multilayer film is oriented in at least one direction to cause fracturing of the top layer to provide a microporous surface exposing the adsorbent silica gel. The fractured top layer is receptive to receiving a printing ink on an exposed surface thereof with enhanced pigment entrapment and rapid ink drying. A single layer film in the form of the top layer, and also oriented in at least one direction also constitutes a part of this invention.
