Document Type and Number:

WIPO Patent Application WO/2014/189030

Kind Code:

A1

Abstract:

The present invention provides: a light-shielding sheet that has a function of shielding light of a specific wavelength and that is capable of preventing a light-shielding substance from migrating into the contents and seeping out of a container; and a container manufactured using the light-shielding sheet. This light-shielding sheet comprises a multilayer structure of three or more layers having at least one light-shielding layer (1) for shielding a specific wavelength, and/or eluate-blocking layer (2) for blocking substances eluted from the light-shielding layer (1). When manufacturing a container from the light-shielding sheet, an eluate-blocking layer (A) (2) is provided at least between the light-shielding layer (1) and an innermost layer (3) or on the innermost layer (3), and an eluate-blocking layer (B) (5) is provided at least between the light-shielding layer (1) and an outermost layer (4) or on the outermost layer (4). The light-shielding layer (1) may further double as an eluate-blocking layer.
