Description of the Related Art Polyolefin resins, especially crystalline polyolefins, are widely used as one of general-purpose resins having many uses because of their excellent physical and chemical properties. Of these applications, stretched films have excellent transparency and mechanical strength for packaging, and sheets have excellent heat resistance and are used in a wide range of fields for food packaging. . However, when it is processed into a polypropylene sheet or film, the resin is crystalline and the crystallization temperature is high, so that it has to be processed at a high temperature. This is usually done, and various measures have been taken to produce a film or sheet by calendering.

As mentioned above, the homopolymer of polypropylene is crystalline and has a high crystallization temperature, so that it is not sufficiently plasticized at the usual calendering temperature, and when calendering at high temperature, the polypropylene homopolymer turns brown. Therefore, polypropylene is mixed with another thermoplastic elastomer to obtain a polyolefin elastomer, and a metal soap is blended (see JP-A-7-26077), or a phosphate ester compound is blended. (See JP-A-6-157833).

する。The present invention will be further described in detail. In the present invention, a homopolymer of polypropylene is used. The homopolymer is superior to the copolymer in mechanical and physical properties such as high rigidity and heat resistance. As the homopolymer of polypropylene used, a measuring method JIS-K-6
The melt viscosity measured at 758 is 0.8 to 3.5 and the crystallization temperature is 110 to 125 ° C. In the present invention, it is desirable that the polypropylene sheet or film obtained does not cause shrinkage or the like during the subsequent heat treatment, and therefore the calendering temperature needs to be set in a temperature range of 170 to 200 ° C. is there. However, when the melt viscosity of the polypropylene homopolymer exceeds 3.5, calendering cannot be performed in such a temperature range, and when it is less than 0.8, the calendering temperature is increased. Although it can be processed, it is not preferable because heat deterioration occurs. Regarding the crystallization temperature of the homopolymer, a crystallization temperature of 110 to 125 ° C. is used for the same reason as the reason for selecting the melt viscosity.

If the amount exceeds, slipping and kneading becomes difficult. Further, a phosphoric acid ester-based stabilizer is added in a proportion of 0.1 to 0.5% by weight. The phosphate ester stabilizer is a stabilizer that is usually added to impart heat resistance or oxidation resistance to a polyolefin resin, and its type is tris (2,4-
Di-t-butylphenyl) phosphite is preferred.
When a phosphate ester stabilizer or calcium stearate is blended alone, slipperiness is less likely to occur, and it is necessary to blend a larger amount, but when blended in a large amount, blowout from polypropylene is caused, for example, the obtained film or It is not preferable because it has a bad influence on printing and adhesive / sticking of the sheet. Further, even if a metal soap other than calcium, such as a stearate of zinc, barium, tin, etc., is used as the lubricant, the calcium stearate is most effective without causing the slipperiness to the left. Then, other compounding agents such as fillers, pigments, antistatic agents, phenolic antioxidants, hindered amine light stabilizers, and ultraviolet absorbers may be added to the composition of the polypropylene homopolymer by a conventional method. good.
