摘要： In a container for a photographic film cartridge having a body and a cap fitted to said body, the improvement comprising that said cap is molded from a resin containing more than 20% by weight of a low-pressure linear low-density polyethylene which is a copolymer of ethylene and butene-1 and has a density of 0.90 to 0.93 g/cm.sup.3 and a melt index of 8 to 60 g/10 minutes.In the case of the molding resin for the cap of the invention, heat resistance is high, and this resin smoothly flow in a molding machine though temperature of the molten resin is relatively low. Accordingly, coloring troubles hardly occur, and molding cycle can be shortened. This resin is also superior in injection moldability, and molding troubles such as roping, camber, kink and deformation are rare. Mold shrinkage is also little. Since fitting strength of the cap and container body is large, the cap is scarcely detached during packaging process. Water vapor permeability of the resin of the cap is little, and moistureproofness of the container is high.

摘要： A spool for a photographic film comprising 50 to 99.8 wt. % of polystyrene resin, 0.05 to 2.2 wt. % of dimethylpolysiloxane and/or modified dimethylpolysiloxane of which a part of methyl groups are substituted by carboxyalkyl groups, 0.5 to 6 wt. % of rubber and 0.05 to 3 wt. % of carbon black having a pH of 5 to 9 and a mean particle size of 10 to 120 m.mu., and the outer surface of the flange of the spool is made rough so that the reflectance of the incident light at an incident angle of 75 degrees is less than 40% in the direction of regular reflection at an angle of 75 degrees.Static frictional coefficient of this spool against metal is small, and thereby photographic film can be drawn out of a photographic film cartridge smoothly to the last. Breakage of the perforations of photographic film does not occur. The outer surface of the flange of the spool is not glossy and its reflectance is low. Accordingly, the light passed through the space between end cap of cartridge and boss of spool does not reach the photographic film in the cartridge.

摘要： A core that is adapted to receive web material such as a wound film roll includes inner and outer coaxial cylinders joined together by a ring plate that extends perpendicular to the longitudinal axes of the inner and outer cylinders. A plurality of radially disposed ribs are positioned between and connected to the inner and outer cylinders. At least one projection is provided on the core at one of various places such as the inner surface of the outer cylinder or the outer surface of the inner cylinder. The projection increases frictional resistance between the mold core and the molded core, thereby ensuring the mold core will be ejected with the core from the mold cavity. The core is manufactured from a resin composition comprising 70 to 30 wt. % of polypropylene resin having a melt index of 10 to 60 g/10 minutes, a bending elastic modulus of more than 8,000 kg/cm.sup.2, an Izod impact strength of more than 2 kg.cm/cm and a Rockwell hardness of more than 70 R, 30 to 70 wt. % of linear low density polyethylene resin having a melt index of 3 to 50 g/10 minutes, a density of 0.910 to 0.935 g/cm.sup.3, an Olsen rigidity of more than 1,500 kg/cm.sup.2 and a Shore hardness of more than 40 D, more than 0.01 wt. % of a lubricant and more than 0.01 wt. % of an antioxidant.
