Abstract: A packaging film includes an inner layer for contacting a packaged subject, a first adhesive layer, a gas barrier layer, a second adhesive layer and an outer layer which are laminated in that order; wherein the inner layer contains linear low-density polyethylene in an amount of more than 40% by mass and no more than 90% by mass and low-density polyethylene and/or high-density polyethylene, does not contain any leachable components and has at least 0.920 g/cm3 density and at least 50 ?m thickness; the first and second adhesive layers, contain antioxidants, and has less than 30 ?m thickness; and the first adhesive layer, the gas barrier layer and the second adhesive layer have less than 30 ?m thickness.

Abstract: The present invention relates to a medical packaging film containing a laminate of a first layer formed of a no-antistatic agent-containing thermoplastic resin formation layer; a second layer formed of a polymer antistatic agent-containing thermoplastic resin formation layer containing a potassium ionomer in an amount of C wt % (10<C<30); and a third layer formed of the thermoplastic resin formation layer, and the laminate provides an amount of a water-elutable alkali component being at most 0.01 mmol equivalent per g in total of 1 cm2 pieces, and in which the first layer has a thickness of L1 m, and the second layer has a potassium ionomer concentration of C?2 vol % and a thickness of L2 m, satisfying the formula 2?L1?(5×L2×C?2)/100+5.
