ABSTRACT:
A container body for photographic film cartridge composed of a resin comprising more than 70 wt. % of polypropylene resin, 0.01 to 2 wt. % of a fatty acid amide lubricant, 0 to 1 wt. % of an antioxidant and 0.01 to 1 wt. % of an organic nucleating agent of which the surface has previously been treated with a stabilizer selected from the group consisting of aliphatic metal salts, metal salts of alkyl lactic acids and metal salts of lactic acid.
The container body of the invention is excellent in dropping strength, transparency and odor. The injection moldability is also excellent, because of good resin fluidity and high crystallization temperature.
