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 &#x3bc;m or more. The sulfur content of the second layer is 1.0 atm % or less.

Package, gas barrier laminate, and packaging body

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 &#xbd; or less of the thickness of the second coating layer; and (condition 3) the number of concave portions having a diameter of 1.5 &#x3bc;m or more per unit area on a surface of the second coating layer opposite to the first coating layer is 2/0.01 mmor less.

Gas barrier laminate and packaging material including the same

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.

Film processing method and film manufacturing method

A transparent conductive gas barrier laminate according to the present disclosure includes a transparent gas barrier film and a transparent conductive layer in this order from outside toward inside. In the laminate, the transparent gas barrier film has a b* value of more than 0 in a L*a*b* color system, and the transparent conductive layer contains a conductive polymer and has a b* value of less than 0 in the L*a*b* color system.

Transparent conductive gas barrier laminate and device including the laminate

A quantum dot protective film for sealing a phosphor, including: a protective layer having foreign matter, the maximum size of which is 100 to 500 &#x3bc;m; and a coating layer formed on one surface of the protective layer, wherein the abundance ratio of the foreign matter with the maximum size of 100 to 500 &#x3bc;m is 0.01 to 5.0 particles/min the protective layer, and the haze value is 20% or higher.
