Title:
ELECTRON BEAM-CURABLE WATER-BASED FLEXO INK FOR SURFACE PRINTING AND BOILABLE RETORT POUCH USING SAME
Document Type and Number:
WIPO Patent Application WO/2019/069736
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a boilable retort pouch that is surface printed using an electron beam-curable water-based flexo ink for surface printing on the outside of the pouch container, wherein the amount of VOC in the ink is almost 0% and the ink has an excellent abrasion resistance and an excellent boilability and retortability. The electron beam-curable water-based flexo ink for surface printing contains a water-based resin (X), an ethylenic double bond-bearing electron beam-curable compound (Y), a pigment, and water, and is characterized in that the mass ratio between the solids fraction of the water-based resin (X) and the solids fraction of the ethylenic double bond-bearing electron beam-curable compound (Y) is within the range of (X)/(Y) = 5/100 to 400/100.
