Abstract: Sealing lacquer for application in a printing process, in particular for sealing packaging parts which can be peeled off from one another. The sealing lacquer has in particular a) 40 to 65 wt % solvent, b) 0 to 10 wt % styrene butadiene block copolymer, c) 8 to 12 wt % styrene alpha methylstyrene, d) 6 to 12 wt % linear and/or radial Tri-block (SBS) block, e) 0 to 10 wt % linear Di-Block (SB) block, f) 15 to 30 wt % polyester, and g) up to 3 wt % antioxidant. The sealing lacquer provides a seal that, whether the seal is opened by peeling, or the packaging is push-through packaging, provides a holding force exhibiting a strength until cohesion failure that is determined by the pressures and temperatures used during sealing.

Abstract: The packaging composite film has an outside and an inside. It also includes a cover layer facing the outside, an inner layer, which faces the inside and has a lower puncture and tear resistance than the cover layer, and a liquid-soluble intermediate layer arranged between the cover layer and the inner layer. To transport liquid from the outside to the liquid-soluble intermediate layer, liquid-transporting openings are provided, which completely penetrate the cover layer and extend in the direction of the inside at least to the intermediate layer, without including the inner layer. A childproof packaging, which is nevertheless easy to open and therefore senior-friendly, can be realized by means of the packaging composite film.

Abstract: The invention relates to a composite for packaging material with a symmetrical structure that consists of plastic/aluminum/plastic. The invention also relates to a container covering with a symmetrical composite structure that consists of polyester/aluminum/polyester, whereby polyethylene terephthalate (PET) is advantageously used as polyester.

Abstract: In a lid, in particular for food packaging, such as yogurt containers or the like, or a label, in particular a label for the neck of a bottle, comprising an embossed aluminum foil or an embossed aluminum composite foil, plastic foil, plastic composite foil, paper foil or paper composite foil, provision is made, in order to attain appealing surface properties, the feasibility of printing even small characters, and an effective separation process, for the embossing to consist of a plurality of approximately parallel embossed lines, wherein preferably at least some embossed line have interruptions and/or at least in sections, different widths and/or different embossing depths.

Abstract: In a printed web-type material, in particular a lid for a container for dairy products, comprising a film of plastics, paper or metal on the visible surface, it is provided, with a view to embodying a material which can be equipped and worked using any hot-sealing varnishes, and more generally to obtaining temperature stability in the printed web of material, that a thermoplastic primer, which is needed for applying the overprint, and the printing ink itself are covered by a varnish of identical or similar composition so that part of the curing agent, which is available in the varnish or applied separately, migrates into the printing ink and the thermoplastic primer, resulting in cross-linking.

Abstract: In a method and an apparatus for the production of a cylindrical embossing sheet that is to be fixed on a rotating clamping cylinder for the manufacture of continuous webs having surface structures, such as holograms, cine-grams, exelgrams, for safety and reliability engineering and decoration purposes, it is provided that the plate-like starting material is bent around an auxiliary implement in particular of cylindrical shape, the diameter of which corresponds approximately to the diameter of the clamping cylinder, with the plate-like starting material being prepared such that, when it is placed around the auxiliary implement, the longitudinal edges butt against each other by a flush joint, and that the plate-like material is fixed in this position, and that the longitudinal edges are then welded together without any gaps by means of a laser.
