<p><P>PROBLEM TO BE SOLVED: To provide a packaging film capable of concealing darkening of patterns resulting from cracks on the surface of an aluminum foil layer, simplifying a simple structure and being excellent in manufacturability; and a packaging bag prepared using the same. <P>SOLUTION: A packaging film 1 is a laminate formed by sequentially laminating a substrate layer 2 which is the outermost layer, a printed layer 3, a hiding layer 4, an aluminum foil layer 5, an intermediate layer 6, and a thermoplastic resin layer 7 which is the innermost layer. A dry laminate layer 8 is formed each between the hiding layer 4 and the aluminum foil layer 5, between the aluminum foil layer 5 and the intermediate layer 6, and between the intermediate layer 6 and the thermoplastic resin layer 7. The hiding layer 4 has a laminate structure including three ink layers of white ink layers 41 and 42, and a silver ink layer 43 from the side of the printed layer 3. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
