Process for manufacturing a film-type packaging material |
摘要 |
A process for manufacturing a flexible packaging material from a single or multi-layer film or film-type laminate containing a sealing layer of powder-type starting material deposited on at least one free surface of the film or film-type laminate. The sealing layer is deposited locally, i.e., over only those parts of the surface to be sealed, and the deposition of the sealing layer takes place by an electrostatic coating process in which coating particles are electrostatically charged and transferred to the film surface to be coated by applying an electric field, and melted and/or hardened to give a coating film in the form of a sealing layer.
