<p><P>PROBLEM TO BE SOLVED: To provide a gas barrier type film which has an excellent gas barrier property for oxygen or the like especially under a high humidity atmosphere, and also, for which the generation of a delamination (an inter-laminar separation of the film after a boiling process or a retort process) is sufficiently suppressed. <P>SOLUTION: This gas barrier type film is constituted by arranging a gas barrier layer containing a polycarboxylic acid based polymer at least on one surface of a polymer film base material through an anchor coating layer containing a polyester based polyol and an aliphatic based isocyanate compound. In this case, an equivalence ratio (OH/NCO) of a hydroxyl group in the polyester based polyol and an isocyanate group in the aliphatic based isocyanate compound is within a range of 1.0/5.0 to 1.0/0.8. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
