Title:
LAMINATED FLEXIBLE PACKAGING MATERIAL AND METHOD FOR MANUFACTURING THE SAME
Document Type and Number:
WIPO Patent Application WO/2008/038716
Kind Code:
A1
Abstract:
This invention provides a laminated flexible packaging material which has been gravure printed using an aqueous color ink, wherein the amount of a white ink used is limited, and, further, a VOC-containing anchor coating agent is not used to reduce the occurrence of VOC and to impart a high level of covering properties and, particularly in gravure printing, a gravure cylinder provided with a diamond-like carbon (DLC) layer as a surface strengthening covering layer instead of a chromium layer is used. There is also provided a method for manufacturing the same. The flexible packaging material comprises a base material film, an aqueous gravure color ink layer, an anchor coating agent layer, a white pigment-containing resin layer, and a sealant layer stacked in that order. The aqueous gravure color ink layer is formed by gravure printing using a gravure cylinder provided with a diamond-like carbon film.
