PURPOSE:To provide titled resin film which has excellent weathering resistance over a long period of time when the film is used as a covering material outdoors, by a method wherein a specified stabilizer and a specified inorg. fine powder are blended with a thermoplastic synthetic resin film. CONSTITUTION:(A) 0.1-2wt% of a hindered amine stabilizer (e.g. 2,2,6,6-tetraalkyl-piperidine derivative having substituent at 4-position and a MW of not less than 250) and (B) 0.5-20wt% of an inorg. fine powder having polarity and a surface area of at least 10cm<2>/g (e.g. a powder of silicic acid, alumina or zeolite), are kneaded with a resin such as a polyolefin, a polystyrene or a polyvinyl chloride. The kenaded product is molded into a film by an inflation method, T-die method, etc. |
