A method for manufacturing a liquid paper container with digital printing, and a method for manufacturing a cylindrical container using a body member with digital printing.

摘要

PROBLEM TO BE SOLVED: To produce a variety of liquid paper containers with digital prints at small lots.;SOLUTION: A lamination package material 20 is formed by sequentially stacking a resin layer 6, a paper layer 5, an adhesive resin layer 4, a gas barrier layer 2, and a sealant layer 1, the resin layer 6 is pattern-coated with a primer layer 7 on a part other than a part sealed during forming in a subsequent step, an ink layer 8 is formed by executing digital printing for applying liquid toner on the primer layer 7, and a protective layer 9 is formed on the ink layer 8. A liquid paper container is formed through thermal weld molding by the lamination package material in an area other than an area formed by sequentially stacking the protective layer 9, the ink layer 8, and the primer layer 7.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
