REFLECTIVE FILM, AND REFLECTIVE SHEET FOR BACK LIGHT COMPRISING THE SAME

摘要

Disclosed is a reflective film produced by forming a film from a resin composition comprising 100 parts by mass of a polyolefin component (A) comprising a polyolefin having stereoregularity and a modified polypropylene and 40 to 240 parts by mass of a biodegradable polyester component (B), and stretching the film. Also disclosed is a reflective sheet for a backlight, which comprises the reflective film. It becomes possible to provide a polyolefin-polyester reflective film having a high reflection property without the need of incorporating any filler into a raw material resin composition, or without the need of additionally providing any reflective coating layer on the surface of the resulting film for the purpose of providing an optical property (e.g., reflectivity) to the resulting film, and becomes also possible to provide a reflective sheet for a backlight which comprises the reflective film.
