Abstract
A laminated material having a barrier film containing a barrier layer on at least one surface of a substrate film that is a silicon oxide film having an atomic ratio in a range of Si:O:C=100:140 to 167:20 to 40, peak position of infrared-ray absorption due to Si—O—Si stretching vibration between 1060 to 1090 cm−1, a film density in a range of 2.6 to 2.8 g/cm3, and a distance between grains of 30 nm or shorter.
Claims6
A laminated material comprising a barrier film provided with a barrier layer on at least one surface of a substrate film which is composed of a resin, wherein the barrier layer is a silicon oxide film having an atomic ratio in a range of Si:O:C=100:140 to 167:20 to 40, peak position of infrared-ray absorption due to Si—O—Si stretching vibration between 1060 to 1090 cm−1, a film density in a range of 2.6 to 2.8 g/cm3, and a distance between grains in a range of 10 to 30 nm, and a conductive layer is provided on at least one surface of the barrier film, wherein an oxygen transmission rate thereof is 0.1 cc/m2/day·atm or less, and a water vapor transmission rate thereof is 0.1q/m2/day or less.
