摘要： Provided is a method for producing a gas barrier paper packaging material which can impart sufficient gas barrier properties even when a barrier coating agent for forming a barrier layer is applied in a dry amount of 2 g/m2 or less. The method for producing a gas barrier paper packaging material at least includes: a barrier layer forming step of applying a barrier coating agent to one side of a sealant film to form a barrier layer; and a lamination step of laminating the barrier layer and a paper substrate layer via an adhesive layer.
