An aliphatic polyester film is obtained by melt-extruding an aliphatic polyester as a film, controlling the entrained air stream between a casting drum and the film while inhibiting the variations of the film edge portion landing points on the casting drum, and subsequently bringing the film into contact with the casting drum over the entire width of the film.

Method for producing aliphatic polyester film

A biaxially oriented white polypropylene film containing a core layer (layer A) and a skin layer (layer B), said layer B is laminated at least on one surface of said layer A, wherein said layer A contains a polypropylene resin having &#x3b2;-crystal activity and 1 to 20 mass % particle (a) having an average dispersed diameter of 60 to 400 nm, and wherein, said layer B contains a polypropylene resin and 0.05 to 5 mass % particle (b) of an average dispersed diameter of 1 to 4 &#x3bc;m. The present invention provides a biaxially oriented white polypropylene film excellent in film quality and productivity and capable of making sensitivity and productivity compatible in a high level when used as a base for a receiving sheet, and a receiving sheet for thermal transfer recording made thereof.
