Abstract: To provide a film superior in hand tearability and linear cutting efficiency that can be produced without need for a complicated blending of resin raw materials and high-grade processing facilities. There is provided a film having an average distance between the local apexes in any one direction of 8 ?m or less.

Abstract: [PROBLEMS] To provide a film superior in hand tearability and linear cutting efficiency that can be produced without need for a complicated blending of resin raw materials and high-grade processing facilities. [MEANS OF SOLVING PROBLEMS] There is provided a film having an average distance between the local apexes in any one direction of 8 ?m or less.

Abstract: To provide a fiber made of a vinyl chloride resin which is excellent in heat resistance and thus hardly shrinks thermally even at a temperature exceeding 100° C. The fiber obtained by melt-spinning a resin composition comprising a vinyl chloride resin and from 1 to 300 parts by mass of a polyester resin based on 100 parts by mass of the vinyl chloride resin, wherein the vinyl chloride resin has a viscosity average polymerization degree of from 600 to 2,500; the polyester resin is a polylactic acid type resin; and the polyester resin has the melting point of from 100 to 300° C.

Abstract: [Problems] To provide a method of packing fiber for artificial hair, while suppressing generation of folding mark during packaging, transportation and storage and yet preserving preferable processability and hairdressing characteristics. [Means for Solving Problems] There is provided a method of packing fiber for artificial hair, characterized by packing the artificial hair fibers in a packaging container at a filling density of no lesser than 0.1 kg/l and no more than 0.8 kg/l. Further in the packing method, the pressure of the packed artificial hair fibers applied to the top face of the packaging container is adjusted to no lesser than 0.1 kPa and no more than 8.0 kPa.

Abstract: A vinyl chloride/vinyl acetate copolymer characterized in that it has a peak at a signal position of from 6.0 to 8.0 ppm in the .sup.1 H-NMR measurement.
