Abstract: A process for manufacturing a packaging material with at least two films (12,16) or foils bonded together via at least one adhesive layer (13) to form a multi-layer laminate (10) is such that at least one adhesive layer is an electron-beam-curable adhesive and the laminate (10) is radiated with electrons in order to cure the adhesive. The laminate is particularly suitable for manufacturing pouch-type forms of packaging, in particular for snack foods. The production of laminate using electron-beam-curable adhesive results in a significant reduction in throughput time and in a reduction of solvent emissions by replacing solvent-based adhesives with electron-beam-curable adhesives.

Abstract: A packaging container is such that a laminate features a film-shaped substrate bonded to a hot-sealing layer via a contact adhesive layer for easy opening and reclosing the container—arranged between an adhesive layer of permanent adhesive and a hot-sealing layer and is bonded to itself via a sealing seam or to another film to form a pouch or, as lid, bonded to the edge of a pouch. For the production of the laminate, the film-type substrate is coated—via liquid-film coating using the curtain coating or slide-coating method—with a multi-layer liquid film comprising at least an adhesive layer, the contact adhesive layer and the cohesively rupturing hot-sealing layer.

Abstract: 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.

Abstract: A composite plastic film comprises a plastic film which is coated, as desired at least on one side, with ceramic material deposited using a vacuum thin layer deposition process and a plastic layer deposited by extrusion coating on the plastic film or on the ceramic layer which may be present, such that the ceramic layer is situated between the plastic film and the plastic layer deposited by extrusion coating. In order to improve the strength of bonding, a metal layer of chromium, aluminum, nickel, titanium, iron, molybdenum or an alloy made up from at least two of these metals is provided, as an aid to bonding, between the plastic film or on the ceramic layer which may be present and the plastic layer deposited by extrusion coating. A thin metal layer deposited in such an amount that it has a thickness of approximately 0.1 to 0.5 nm corresponding to a monatomic coverage is sufficient for this purpose.

Abstract: In a process for production of an aluminum foil (10) coated with sealable and sterlisable plastic (14) based on polypropylene (PP) or polyethylene (PE), the plastic (14) is coextruded with an adhesion-promotion agent (16) and combined with an aluminium foil (24) between two rollers (20, 22). The aluminium foil (10) coextrusion-coated in this way, to increase the adhesion strength between the aluminium foil (24) and the plastic layer (14), then passes continuously through an oven (26) with temperature (TO) set such that the temperature of the plastic layer (14) and the adhesion-promotion agent (16) lies above the crystallite melt point (TK) of the plastic. The coated aluminium foil heat-treated in this way, after emerging from the oven (26), is cooled shock-like such that the crystalline proportion at least in the surface area of the cooled plastic layer (14) and the crystallites in this area are as small as possible.
