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.

摘要： A package for diazo thermosensitive recording materials coiled round a core, which comprises a packaging paper being a water vapor permeability of more than 50 g/m.sup.2.24 hours and comprising a light-reflecting paper layer located as outer layer and a light-shielding paper layer located as inner layer.In the package of the invention, the packaging paper shields the recording material from the external heat and light. When internal humidity is increased such as by heating of the package such as higher than 50.degree. C., moisture passes through the packaging paper to the outside. Accordingly, fogging by precoupling of the packaged diazo thermosensitive recording materials, irrespective of the fixation type or not, is remarkably decreased, and the quality of the recording material can be maintained for a long period during storage.
