摘要： This decorative film is to be bonded to a resin molded body by means of thermoforming, and comprises a sealing layer (I) that contains a polypropylene resin (A) and a layer (II) that contains a polypropylene resin (B). The polypropylene resin (A) satisfies the requirement (a1), while the polypropylene resin (B) satisfies the requirement (b1). (a1) The melt flow rate (MFR (A)) (at 230° C. under a load of 2.16 kg) is more than 0.5 g/10 minutes. (b1) The melt flow rate (MFR (B)) (at 230° C. under a load of 2.16 kg) and the MFR (A) satisfy relational expression (b-1). MFR (B)

摘要： The present invention relates to a polypropylene resin composition for a microporous film which can reduce the product defect rate due to stabilization of porous formation by stabilizing film formation and also can obtain a film suitably usable for a separator, a filtration membrane, a separation membrane and a filter since the microporous film can be thinned due to high rigidity, and more specifically, relates to a polypropylene resin composition for a microporous film wherein the composition comprises 5 to 30% by weight of polypropylene resin (X) having specific MFR, molecular weight distribution Mw/Mn by GPC, melt tension (MT), branching index g′ and mm fraction of the propylene unit triads by 13C-NMR, satisfying specific conditions concerning gels and having a long chain branched structure and 95 to 70% by weight of polypropylene resin (Y) having a specific MFR and excluding the polypropylene resin (X).
