2. Description of the Related Art Polypropylene is widely used as a resin for producing films and general molded products because it has excellent mechanical properties and heat resistance. Furthermore, since polypropylene is particularly excellent in the hinge effect, it is suitable for the production of products such as file binders and cases which require an integral hinge structure. However, products made from polypropylene have a relatively low impact strength at normal use temperatures and are known to fracture brittlely at temperatures below -5 ° C. In addition, various methods have been devised to eliminate the drawback. For example, the "polypropylene composition" in Japanese Patent Publication No. 64-11061 discloses 40 to 98 parts by weight of isotactic polypropylene and 60 to 2 parts by weight of a density of 0.920.
-0.935 A binary mixture obtained by mixing linear low density polyethylene in a molten state using an extruder is defined, and these compositions are said to have excellent impact strength. It is a thing.

Further, regarding the "polypropylene composition" disclosed in Japanese Patent Publication No. Sho 64-11061 described in the above-mentioned prior art, although the impact resistance of conventional polypropylene is improved, the density is 0.920. ~
It is necessary to limit it to the range of 0.935 linear low-density polyethylene, and when linear low-density polyethylene having a density of less than 0.920 is used, the impact strength improvement is extremely small. There is a drawback that it is inferior in strength compared to block copolymers, and especially thin sheets that require a certain rigidity such as stationery files and binders, cases, packaging containers, etc. can not be practically used.

Also, as a guide for reducing punching at the low temperature, punching for attaching the fasteners, and cracks when the file is dropped, at -20 ° C, it is desirable to have a low temperature resistance with a DuPont impact value of 3.0 kg · cm. Impact resistance is required.

The PP ratio is 0.25, which is a value larger than 0.2, but the MFI of the polypropylene used is MFI PP = 8.0.
