POLYAMIDE RESIN COMPOSITION, FILM AND FILM LAMINATE COMPRISING SAME, AND PELLET MIXTURE

원문 (중국어)

Provided are: a polyamide resin composition, which can provide a film that does not have poor appearance arising from film gels and has excellent transparency, puncture strength, and pinhole resistance and which makes material recycling possible; and a film and a film laminate that utilize the polyamide resin composition. A polyamide resin composition comprising, with respect to 100 mass % of the polyamide resin composition, 70-95 mass % of an aliphatic polyamide resin (A), 5-30 mass % of an ethylene/C3-C8 α-olefin copolymer (B) that has functional groups, and 0-5 mass % of another component (C), wherein: the ratio of the number of methylene groups to the number of amide groups in the aliphatic polyamide resin (A) is 3-11; and when the number average molecular weight and weight average molecular weight by GPC measurement of the polyamide resin composition are Mn and Mw, respectively, Mn is 25,000-46,000, and Mw/Mn is 1.5-3.0.
