1. A package, comprising:
a bag main body having an inner surface;
at least one mouth part member joined to the bag main body; and
a liquid content accommodated in the bag main body,
wherein the bag main body of the package has, as a forming material, a laminate consisting essentially of:
a water vapor barrier layer made of polychlorotrifluoroethylene;
a sealant layer comprising a polyethylene layer and a cyclic olefin resin layer disposed adjacent to each other, wherein the cyclic olefin resin layer is disposed to be the innermost side of the laminate; and
an interlayer positioned between the water vapor barrier layer and the sealant layer,
wherein the laminate is formed into a bag shape by bonding sealant layers facing each other,
the mouth part member is joined to the bag main body by being sandwiched between the sealant layers facing each other,
a thickness of the water vapor barrier layer is within a range of 15 μm to 25 μm,
a thickness of the sealant layer is within a range of 30 μm to 60 μm,
a volume V of the content accommodated inside the bag main body is 0.1 to 20 (cm3),
a relationship between an area S (cm2) of the bag main body which comes into contact with the liquid content accommodated inside the bag main body and the volume V (cm3) satisfies (Formula I):
0.05≤V/S≤0.25,  (Formula I)
wherein the area S is a total area of the inner surface of the bag main body.
