PROBLEM TO BE SOLVED: To provide a packaging material for a dry pack product which is excellent in oxygen barrier properties while microwave heating and retort sterilization are available, catches residual oxygen in a container, and also is excellent in contents storage properties over a long time. SOLUTION: The packaging material for the dry pack product comprises: an inorganic substance vapor-deposited biaxially oriented polyester film; a printing layer; a biaxially oriented polyamide film; a titanium dioxide-containing unoriented polyolefin film; an oxygen absorption layer made of a composition of a polyolefin and an iron-containing oxygen absorbent; and a titanium dioxide-containing unoriented polyolefin film which are arranged in turn from the outermost layer. The printing layer has a solid printing layer produced by applying a titanium dioxide-containing printing ink at least twice. COPYRIGHT: (C)2007,JPO&INPIT
