AI Technical Summary

Problems solved by technology

When the gas-barrier film is laminated, for example, when the gas-barrier film is laminated with the surface of the deposited layer facing inward, carbon dioxide gas can hardly escape, so a diameter caused by carbon dioxide gas will be formed in the adhesive layer. Fine bubbles of 100 microns or less, which make the film opaque
This in turn causes a problem that the laminated film cannot be used as a packaging material in the packaging fields such as food, pharmaceuticals, electronic components and optical parts that require high transparency, especially in the optical field that requires high transparency.

Embodiment 1

[0123] As a substrate, a 12 micron thick biaxially oriented PET film was prepared. This PET film was placed in an electron beam heating type vacuum deposition apparatus, metallic aluminum was evaporated, and oxygen gas was supplied to deposit a 15 nm thick aluminum oxide layer on one surface of the PET film.

[0124] The following coating agents were then prepared.

[0125] Preparation of coating agent

[0126] First, 89.6 g of hydrochloric acid (0.1 N) was added to 10.4 g of tetraethoxysilane, and the mixture was hydrolyzed for 30 minutes with stirring, thereby preparing a hydrolyzed solution having a solid content of 3% by weight in terms of silica, This solution was used as the first solution.

[0127] Then, as a second solution, a 97% by weight aqueous solution of isopropanol (wherein the weight ratio of water and isopropanol is 90:10) and 3% by weight of polyvinyl alcohol were mixed.

[0128] The first solution and the second solution were mixed at a weight mixing rati...

Abstract

The transparent gas-barrier laminated film of the present invention comprises at least two transparent gas-barrier films and a 1-30 micron thick adhesive layer formed on at least one of the transparent gas-barrier films.

Description

technical field [0001] The present invention relates to, for example, a transparent laminated film which has high gas barrier properties against oxygen and water vapor and which is useful as a packaging material requiring high transparency such as food, pharmaceuticals, electronic components, and optical parts; and utilizing the laminated film Electroluminescent elements, electroluminescent display devices and electrophoretic display panels. Background technique [0002] Packaging materials used for packaging in the food sector and in non-food product sectors such as pharmaceuticals, electronic components and optical components must resist the effects of oxygen and water vapor permeating through the packaging material and other gases that change the properties of the contents , in order to prevent changes in the properties of the contents and maintain their functions and properties; and also require packaging materials to have gas barrier properties su...
