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.

Abstract: A treatment method performed by a film processing apparatus including: a first discharge electrode unit and a second discharge electrode unit respectively including magnets that form a magnetic field; and an AC power source capable of alternately switching polarities of the first discharge electrode unit and the second discharge electrode unit. In the treatment method, a predetermined surface treatment of a film F is performed by generating a plasma P while alternately switching polarities of the first discharge electrode unit and the second discharge electrode unit by using high-frequency power supplied from the AC power source.
