PROBLEM TO BE SOLVED: To provide a nonadsorptive member reduced in an adsorption amount of a trace effective component. SOLUTION: This nonadsorptive member is laminated with a base material layer, an aluminum foil, an adhesive layer and a nonadsorptive layer, an arithmetic mean coarseness Ra of the adhesive layer laminated with the nonadsorptive layer is 1.5μm or less, and the nonadsorptive layer comprises a mixture of an ethylene-vinyl acetate copolymer and an inorganic filler. A heat-seal layer is part-coated further on the nonadsorptive layer, to obtain a nonadsorptive packing material of superior reclosability. COPYRIGHT: (C)2010,JPO&INPIT |
