Title:
GAS BARRIER FILM, WATER VAPOR BARRIER PROPERTY EVALUATION TEST PIECE, AND METHOD FOR EVALUATING VAPOR BARRIER PROPERTIES OF GAS BARRIER FILM
Document Type and Number:
WIPO Patent Application WO/2019/049618
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a gas barrier film capable of highly accurately detecting long stripe-like fine scratches and the periodicity of a gas barrier property change appearing in a lateral stage shape. The gas barrier film 1 of the present invention is provided on a long resin base material 4 with: a gas barrier layer 5; and first and second water vapor barrier property test region parts 10 and 20, wherein the first and second water vapor barrier property test region parts 10 and 20 each include first or second moisture reactive metal layers 12 and 22, and first or second water vapor impermeable layers 11 and 21 for sealing the first and second moisture reactive metal layers 12 and 22, and when the first moisture reactive metal layer 12 and the second moisture reactive metal layer 22 are viewed from at least one of the longitudinal direction and the width direction of the resin base material 4, there is a portion L1 in which the first moisture reactive metal layer 12 and the second moisture reactive metal layer 22 partially overlap each other.
