REFLECTIVE FILM OF ALIPHATIC POLYESTER RESIN AND ITS PRODUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a reflective film which has excellent light reflecting properties, is prevented from yellowing with the passage of time when used, and keeps the light reflecting properties.

SOLUTION: The reflective film of an aliphatic polyester resin contains the aliphatic polyester resin of a reflective index below 1.52 as a main component and is obtained by extruding a resin composition containing a fine powder filler at 230°C or below into a sheet. The filler can be surface-treated. The filler can be titanium oxide, and its content in the resin composition can be 10-60 mass%.
