摘要： A package according to the present invention comprises: a packaging body constituted by a sheet that includes a gas barrier laminate and a sealant; and contents that are accommodated in the packaging body and that contain a sulfur-containing amino acid. The gas barrier laminate comprises: a resin substrate; a first layer containing an inorganic oxide; a second layer containing a carboxylic acid polymer; and a third layer containing a polyvalent metal compound and a resin. The resin substrate, the first layer, the second layer, and the third layer are layered in this order from the outside to the inside of the packaging body. The thickness of the third layer is 0.1 µm or more. The sulfur content of the second layer is 1.0 atm% or less.
