Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a plastic film for an infusion capable of being used as an infusion container prescribed in the Japanese Pharmacopoeia plastic pharmaceutical container test method, by constituting all of plastic films of individual layers of a polyolefin film as the constitutional material of a plastic film laminate. SOLUTION: In the polyolefin film laminate, a protective layer comprising a polyolefin film is laminated on a gas barrier layer which comprises the silicon oxynitiride membrane layer applied to the undercoat agent layer on a biaxially stretched polypropylene (OPP) film. Light transmissivity is 55% or more, a hue (b) value is 5 or less, oxygen gas permeability measured in a dry atmosphere at 40 deg.C is 50 cc/m2.day.atm or less and steam permeability is 2 g/m2.day.atm or less.
