BARRIER FILM AND LAMINATED MATERIAL, CONTAINER FOR WRAPPING AND IMAGE DISPLAY MEDIUM USING THE SAME, AND MANUFACTURING METHOD FOR BARRIER FILM
Abstract:
An object of the present invention is to provide a barrier film having the extremely high barrier property and the better transparency, a method for manufacturing the same, and a laminated material, a container for wrapping and an image displaying medium using the barrier film. According to the present invention, there is provided a barrier film provided with a barrier layer on at least one surface of a substrate film, wherein the barrier layer is a silicon oxide film having an atomic ratio in a range of Si:O:C=100:160 to 190:30 to 50, a peak position of infrared-ray absorption due to Si—O—Si stretching vibration between 1030 to 1060 cm−1, a film density in a range of 2.5 to 2.7 g/cm3, and a distance between grains of 30 nm or shorter. Still more, there is provided a barrier film provided with a barrier layer on at least one surface of a substrate film, wherein the barrier layer is a silicon oxi-nitride film having an atomic ratio in a range of Si:O:N:C=100:80 to 110:40 to 70:30 to 50, a maximum peak of infrared-ray absorption due to Si—O stretching vibration and Si—N stretching vibration in a range of 900 to 1000 cm−1, a film density in a range of 2.7 to 3.0 g/cm3, and a distance between grains of 30 nm or shorter.
