Zusammenfassung:	PROBLEM TO BE SOLVED: To coextrude a multi-layer with good quality while sufficiently maintaining a non-absorptive property of an acrylonitrile copolymer.SOLUTION: This non-absorptive packaging material 1 is a packaging material in which a base material film 2 and a non-absorptive sealant film 3 are sequentially laminated. The non-absorptive sealant film 3 is formed by laminating polyolefin resin 4, adhesive resin 5, and acrylonitrile copolymer resin 6 in this order. An average molecular weight of the acrylonitrile copolymer resin 6 is in a range of 60,000 to 140,000.
