Gas barrier resin film

摘要

A gas barrier film comprising at least a polyamide film and an inorganic deposited layer laminated thereon, wherein the maximum shrinkage percentage after boiling treatment at 95 DEG C for 30 minutes is not more than 3.5%. The gas barrier film of the present invention has excellent gas barrier property and water vapor-proof property even after boiling or retort treatment. Hence, the film of the present invention can serve well as a wrapping material for a wide range of objects that require high gas barrier property, such as food, medical products, industrial materials and the like, and has great industrial value.
