The skin layers each comprise a) at least about 95 wt % of a polypropylene mini-random homopolymer comprising polypropylene, up to 2 wt % ethylene components, and an acid neutralizer in a concentration up to about 5000 ppm, and b) an anti-block agent in a concentration up to about 1 wt %, wherein the anti-block agent comprises at least 95 wt % homopolymer of polypropylene and 1 to 5 wt % of silica having a particle size between about 1 to 3 μm.
