1. A method for producing a package comprising a layered double hydroxide having HS− and/or Sk2− (wherein k represents a positive integer) intercalated among layers, and a packaging material hermetically housing the layered double hydroxide, the method comprising:
preparing a layered double hydroxide having an anion other than HS− and/or Sk2− (wherein k represents a positive integer) intercalated among layers, and a solvent;
making the solvent to contain HS− and/or Sk2− under a nitrogen gas or rare gas atmosphere to provide a solution;
bringing the layered double hydroxide having an anion other than HS− and/or Sk2− (wherein k represents a positive integer) intercalated among layers into contact with the solution under a nitrogen gas or rare gas atmosphere;
separating a solid matter after the contact from the solution, and washing and drying the solid matter, under a nitrogen gas or rare gas atmosphere; and
sealing the solid matter after drying in a packaging material.
