<p>An aliphatic polyester film which has satisfactory slip properties better than those of polylactic acid films, is inhibited from meandering or creasing, retains stiffness, strength, and low heat shrinkability, and optionally has transparency. The film comprises an aliphatic polyester consisting mainly of a polylactic acid polymer, contains inorganic particles, and has an average surface roughness (Ra) of 0.01 < Ra ≤ 0.08.</p> |
