PURPOSE:To obtain the title compsn. which gives a film suitable for packaging with an automatic packaging machine with excellent transparency and rigidity by the air-cooling inflation method, by compounding a resin component consisting of a high-density PE resin and a low-density PE resin with a metal salt of a fatty acid and a specified phosphorus compd. CONSTITUTION:A PE resin compsn. is obtd. by compounding a resin component (A) consisting of a high-density PE resin (a) with a density of 0.950-0.962g/cc, an MFR (at 190 deg.C) of 0.51-1.0g/10min and MI20/MI2 of 10-40 and a low-density PE resin (b) with a density of 0.915-0.930g/cc, an MFR (at 190 deg.C) of 0.1-2.0g/10min, an m.p. of 106-115 deg.C and a melt tension of 5g or large at the wt. ratio a/b of 60/40-80/20 with 0.4-2wt.% metal salt of a fatty acid (B) and 0.03-0.3wt.% phosphorus compd. (C) such as tetrakis(2,4-di-tert-butylphenyl) 4,4-biphenylenephosphonite. By said compounding, a film suitable for packaging with an automatic packaging machine with excellent transparency and rigidity can be obtd. from this resin compsn. by the air-cooling inflation molding method. |
