<p>A thermoplastic resin composition comprising an aliphatic polyester (A) and a polylactic acid polymer (B), the amount of the polylactic acid polymer (B) being 1 to 20 parts by weight, excluding 20 parts by weight, per 100 parts by weight of the sum of both. The composition gives a biodegradable film having a controlled biodegradation rate, in particular, a biodegradable agricultural mulch film, which is suitable for practical use.</p> |
