Abstract

The object of the present invention is to provide an electron beam curable surface printing water-based flexographic ink that uses 0% VOC in the ink as much as possible and is excellent in abrasion resistance and boiling / retorting adaptability. Printed boiling / retorting sachets. A water-based flexographic ink for electron beam-curable surface printing, characterized in that it contains a water-based resin (X), an electron-ray polymerizable compound (Y) having an ethylenic double bond, a pigment, and water, wherein the water-based The mass ratio of the solid content of the resin (X) to the solid content of the electron beam polymerizable compound (Y) having an ethylenic double bond is in the range of (X) / (Y)=5 / 100 to 400 / 100.

Description

technical field

[0001] The present invention relates to a water-based flexographic ink for surface printing that can be used in water-based flexographic printing equipped with electron beam curing equipment, and a boilable / retort pouch using the same. Background technique

[0002] Water-based flexographic printing is widely used for the purpose of imparting decoration and functionality to printed objects.

[0003] In recent years, due to changes in lifestyles such as the increase in the number of double-career households and the number of single-person households in recent years, food pouches, such as gas-displacing pouches for fast food packaging, small pouches for boiling that are compatible with heat treatment, and heat-pressurized pouches. Retort sachets and the like, among which the consumption of boiled / steamed food sachets is increasing year by year.

[0004] As examples of boiling / steaming pouches, packaging materials for food and beverages such as curry, hamburgers...
