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.
