Composition for forming gas-barrier material, gas-barrier material, a method of producing the same, and gas-barrier packing material

摘要

A composition for forming a gas-barrier material, comprising a polycarboxylic acid-type polymer (A) and at least a bifunctional alicyclic epoxy compound (B). The composition for forming a gas-barrier material features excellent gas-barrier property, retort resistance and flexibility, can be cured at a low temperature in a short period of time without affecting the plastic base material, and contributes to improving the productivity.
