PROBLEM TO BE SOLVED: To provide a packaging material which can secure tenacity without deteriorating a gas barrier property and visibility from outside.SOLUTION: A packaging material is composed of a laminate, which comprises at least a film 1 printed on its surface or back surface, a barrier film 8 having a transparent barrier layer, a multi-layer nylon layer 11 including a nylon layer(s), and a polyethylene layer 13 in this order. Furthermore, the transparent barrier ayer is formed by laminating: as a first layer, a vapor-deposited layer 6 comprising an inorganic compound; and, as a second layer, a gas barrier coating film 7 obtained by coating and heat drying a coating agent obtained by adding a silane monomer to a main agent comprising an aqueous solution or a water/alcohol solution of a water-soluble polymer and at least either of (a) one or more alkoxides and hydrolysates of the same, or both thereof, or (b) tin chloride. |
