Abstract: A gas barrier laminate including a resin substrate, a first coating layer containing a carboxylic acid polymer; and a second coating layer containing a polyvalent metal compound and a resin, laminated in this order; a ratio of a thickness of the second coating layer to the first coating layer in the range of 1.0 or more and 4.0 or less; and the second coating layer satisfies at least one of the following: (condition 1) a haze of the second coating layer is 8% or less; (condition 2) a surface roughness Ra of the second coating layer is ½ or less of the thickness of the second coating layer; and (condition 3) the number of concave portions having a diameter of 1.5 μm or more per unit area on a surface of the second coating layer opposite to the first coating layer is 2/0.01 mm2 or less.

Abstract: 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.
