Microtextured films with improved tactile impression and/or reduced noise perception

A film layer having a micro-textured surface, comprising:

• (a) a continuous phase comprising one or more thermoplastic polymers, wherein at least one of the thermoplastic polymers is a low-modulus polymer having a 2% secant modulus from about 30 MPa to about 75 MPa and wherein the film layer comprises from 10 wt % to 100 wt % of the low modulus thermoplastic polymer;
• (b) a discrete phase comprising a thermoplastic starch, wherein the film layer comprises from 10 wt % to 45 wt % of the thermoplastic starch;
• (c) a surface migratory agent having a concentration from 0.05 wt % to 0.5 wt % by weight of the film layer;
• and
• wherein the film layer has a 2% secant modulus in the MD direction greater than 140 MPa.

A method of making a film layer having a micro-textured surface, comprising:

• extruding a heated film composition through an annular die to form a tube comprising the film composition, wherein the film composition comprises from 10 wt % to 45 wt % of a thermoplastic starch, a surface migratory agent having a concentration from 0.05 wt % to 0.5 wt % by weight of the film composition, and from 10 wt % to 100 wt % of a low modulus thermoplastic polymer having a 2% secant modulus from about 30 MPa to about 75 MPa;
• cooling the tube;
• and
• forming a film layer from the tube, the film layer having a micro-textured surface and a continuous phase and a discrete phase comprising the thermoplastic starch, wherein the film layer has a has a 2% secant modulus in the MD direction greater than 160 MPa.
