Description

201224035 VI. [Technical Field] The present invention relates to a resin composition which can be suitably used in applications requiring transparency and moisture resistance, and a sheet obtained by molding thereof. [Prior Art] In addition to the requirements for thermoformability, rigidity, and impact resistance, it is also required to prevent moisture. The main material of the sheet, such as transparency, has been mainly used for the purpose of collecting polyethylene (hereinafter also referred to as "PVC"). However, since the vaporized hydrogen gas generated by the combustion of pvc deteriorates the combustion furnace, or the gasification of hydrogen gas pollutes the environment, the alternative material of PVC is continuously studied. As a substitute for such PVC, linear low-density polyethylene, high-density polyethylene, polypropylene, and the like have been proposed. However, the linear low-density polyethylene is excellent in transparency, but its moisture-proof property is not sufficient, and it is difficult to be an optimum resin from the viewpoint of stability of the contents during long-term storage. Although polypropylene is superior in moisture resistance to linear low-density polyethylene, there is still a problem that it does not have sufficient moisture resistance for applications requiring more moisture resistance. On the other hand, high-density polyethylene is superior in moisture resistance to linear low-density polyethylene or polypropylene, but has a problem of poor transparency. Therefore, in order to improve the transparency of the yam and yttrium, it is disclosed in Patent Document 1 that the resin obtained by blending a nucleating agent with a high density polyethylene having a density of 0.942 to 0.965 g/cm 3 is 100136921 3 201224035. Composition. Further, Patent Document 2 discloses a resin composition obtained by blending an alicyclic saturated hydrocarbon resin having no polar group in a high-density polyethylene having a density of 0.94 to 0.97 g/cm3.

As described in the above Patent Document 1, it is difficult to obtain sufficient transparency in the formation of a sheet material by blending a nucleating agent into a high-density polyethylene. Further, by blending the alicyclic saturated hydrocarbon resin having no polar group in the high-density polyethylene as in the above-mentioned Patent Document 2, although the moisture resistance is slightly improved, it is difficult to obtain sufficient transparency at the time of sheet formation. Therefore, the object of the present invention is to provide a novel resin composition which can impart sufficient transparency and moisture resistance at the time of sheet forming in view of the problems of the prior art as described above. (Means for Solving the Problem) The present invention provides a resin composition comprising a metallocene ethylene-based polymer having a density of 0 936 to 0.948 g/cm 3 and a heat of crystal fusion of 15 〇 2 〇〇 J/g (A) And the ratio of (B) in the total yttrium of the above (a) and (b) is 〇.〇1 to 3 〇% by mass. 100136921 201224035 (Effect of the Invention) The resin composition of the present invention can impart sufficient transparency and moisture resistance at the time of sheet formation, and therefore can be used as a packaging material such as a pharmaceutical or a pastry, and requires transparency and prevention. The material of the wet packaging material. Further, it can be suitably used as a protective material for an electronic device requiring high transparency and moisture resistance such as a solar cell sealing material.
