PROBLEM TO BE SOLVED: To provide a quality keeping agent package which maintains the intrinsic capacity by seal-packaging quality keeping agent immediately before it is used, and is manufactured at low cost in an easily handling manner by easily peeling a non-permeable packaging material when the agent is used. SOLUTION: In a quality keeping agent package 11, a quality keeping agent body 9a to absorb or generate gas is sealed in a permeable packaging material 5 to constitute a quality keeping agent 9, a non-permeable packaging material 1 of the shape substantially same as that of the permeable packaging material 5 is laminated on a surface of the permeable packaging material, and the quality keeping agent 9 is seal-packaged by heat seal. Easy-peel layers 4 and 8 are laminated on both side or a single side of an overlapping surface between the permeable packaging material 5 and the non-permeable packaging material 1 so that a part or the whole of the non-permeable packaging material 1 can be peeled from the permeable packaging material 5 when the agent is used.
