ELECTROSTATICALLY ASSISTED PRINTING OF A PACKAGING MATERIAL LAMINATE FOR DIMENSIONALLY STABLE FOOD AND DRINK PRODUCT CONTAINERS WITH A MULTITUDE OF PRINTING UNITS.

摘要

The invention relates to a method (100) comprising, as method steps, a) providing i) a sheetlike composite (300) comprising, as mutually superposed layers, A) a carrier layer (303), B) a barrier layer (305), and C) an inner polymer layer (306), ii) n components (603, 605, 607), where, for every i from 1 to n, A) the ith component (603, 605, 607) comprises an ith component surface (801), and B) the ith component surface (801) comprises a multitude of recesses (802), wherein the recesses (802) each comprise a composition (803) comprising a colourant, wherein the n components (603, 605, 607) rotate in one method direction, wherein, for every i from 1 to (n-1), the (i+l)th component (603, 605, 607) is arranged after the ith component (603, 605, 607) in the method direction; and b) moving the sheetlike composite (300), such that a first region of the sheetlike composite (300) runs through the following sequence of steps comprising steps b) i) (103, 105) and b) ii) (104, 106) successively for every i from 1 to n in ascending sequence: i) altering an electrical voltage between the first region and the ith component surface (801), and ii) contacting an outer surface (301) of the sheetlike composite (300) in the first region with the ith component surface (801); where n is a natural number and is at least 2, where i is a natural number. The invention further relates to an apparatus (600), to a printed sheetlike composite (400), to a container precursor (900) and to a closed container (1000).
