POLYLACTIC ACID RESIN COMPOSITION, POLYLACTIC ACID FILM, MOLDED ARTICLES, ORIENTED FILM AND HEAT-SHRINKABLE LABELS MADE BY USING THE POLYLACTIC ACID FILM, AND CONTAINERS WITH THE LABELS

摘要

The present invention provides a polylactic acid-based resin composition comprising: 50-90 mass % of a polylactic acid-based resin (A) ; and 10-50 mass % of a polyolefin-based resin (B), wherein the heat quantity of crystallization of the polyolefin-based resin (B) is 40 J/g or less as measured by using differential scanning calorimetry as measured in a thermal process comprising the steps of: heating up to 200 °C at a heating rate of 10 °C/min; keeping the temperature at 200 °C for 5 minutes; and cooling down to the room temperature at a cooling rate of 10 °C/min. The invention also provides: a polylactic acid-based film, a molded product using the film, an elongated film, a heat-shrinkable label, and a container having the label thereon.
