Process for manufacturing a multi-layer film-type laminate for packaging materials

Abstract

A production device ( 10 ) for manufacturing a multi-layer film-type laminate. The production device ( 10 ) includes a continuous feed production line for film-type materials with an uncoiling and coiling system for uncoiling and coiling the films or film-type laminates in question present in roll form. The production device ( 10 ) also contains one laminating ( 1 ) and/or extrusion station for manufacturing a multi-layer film-type laminate, at least one printing station ( 2 ) and at least one sealing layer station ( 4 ). The individual stations are arranged in-line as integral modules of the production device ( 10 ). Thereby, the printing station ( 2 ) and the sealing layer station ( 4 ) contain apparatus for coating the film or film-type laminate using an electrostatic coating process.
