Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a packaging material which can simply form a printing layer having excellent adhesiveness by printing after having used an inkjet method, and has excellent heat resistance without coating OP varnish on the printing layer; and a method for manufacturing the same.SOLUTION: A packaging material has a base material containing a metal foil and/or a resin film, a coating resin layer laminated on at least a part of one surface of the base material, and a printing layer printed with ink containing 2-(2-vinyloxyethoxy)ethyl (meth)acrylate on at least a part of the surface of the coating resin layer. A content of the 2-(2-vinyloxyethoxy)ethyl (meth)acrylate in 100 wt.% of a solid content of the ink is 20-65 wt.%.SELECTED DRAWING: None 【課題】インクジェット法を用いた後印刷により簡便に密着性に優れた印刷層を形成でき、しかも印刷層にＯＰニスを被覆しなくても耐熱性が良好な包装材、並びにその製造方法を提供する。【解決手段】金属箔及び／又は樹脂フィルムを含む基材と、当該基材の一方面の少なくとも一部に積層された被覆樹脂層と、当該被覆樹脂層の表面の少なくとも一部にアクリル酸２−（２−ビニロキシエトキシ）エチルを含有するインクにより印刷された印刷層とを有し、前記インクの固形分１００重量％中の前記アクリル酸２−（２−ビニロキシエトキシ）エチルの含有量が２０〜６５重量％であることを特徴とする包装材。【選択図】なし
