<p>Disclosed is a polylactic acid resin film that has excellent heat sealing properties, impact resistance, and transparency, is highly suitable for use as a packaging material, is further suitable for use in an inflation method using a relatively inexpensive equipment, and is highly cost effective. The polylactic acid resin film is characterized in that the polylactic acid resin film comprises at least one heat seal layer of a composition containing not less than 65% by mass and not more than 95% by mass of a polylactic acid resin (A) and not less than 5% by mass and not more than 35% by mass of an aliphatic polyester (other than the polylactic acid resin (A)) and/or an aliphatic aromatic polyester (B) that have a melt mass flow rate (MFR (g/10 min)) of not less than 3 (g/10 min) and not more than 9 (g/10 min) under conditions of a temperature of 190°C and a load of 2.16 kg, and has a heat seal strength between heat seal layers (Hs) of not less than 7 (N/15 mm).</p> |
