A system for packaging a plurality of packing units on a pallet, including: a plurality of packing units made of packaging sleeves and packing-unit overwrapping, the packing-unit overwrapping enclosing the packaging sleeves; a pallet for stacking the packing units; pallet overwrapping, which encloses the packing units stacked on the pallet; and an insert provided, where: the packaging sleeves are produced from a composite material; the front side and the rear side of each packaging sleeve are separated from one another by folding edges, along which the packaging sleeve is folded flat; each packaging sleeve has two openings which are arranged on opposite sides of the packaging sleeve; each packaging sleeve has a longitudinal seam which connects two edges of the composite material to form a peripheral packaging sleeve; and the pallet overwrapping is produced from a plastics film.

System for packaging a plurality of packages on a pallet

The present invention relates to a method comprising as method steps: a) providing a sheetlike composite precursor comprising a carrier layer; b) overlaying the sheetlike composite precursor on an outer face of the sheetlike composite precursor with a liquid first polymer composition; c) hardening the liquid first polymer composition, thereby obtaining a first polymer layer; and d) overlaying the sheetlike composite precursor on the outer face of the sheetlike composite precursor with a liquid second polymer composition; wherein the first polymer layer in method step d) comprises an isocyanate content in a range from 0.1% to 50% by weight, based on the weight of the first polymer layer. The invention further relates to a sheetlike composite obtainable by the method; a container precursor and a closed container, each comprising the sheetlike composite; and to uses of a liquid primer and the sheetlike composite.

Method of printing a laminate for production of dimensionally stable food and drink product containers with application of a primer having an excess of isocyanate groups

The invention relates to a sheetlike composite comprising, as layers of a layer sequence in the direction from an outer face of the sheetlike composite to an inner face of the sheetlike composite, a) a first polymer layer, b) a carrier layer, and c) a barrier layer, wherein the first polymer layer is characterized by a ratio of a proportion of aromatic groups in the first polymer layer to a proportion of carbonyl groups in the first polymer layer in a range from 0.18 to 0.34. The invention further relates to processes for producing a sheetlike composite, a container precursor and a closed container and to the aforementioned process products; to a further container precursor; to a further closed container; and to uses of the sheetlike composite, of a hardener and of a printing ink.

Sheetlike composite for producing dimensionally stable food and drink product containers having a polymer layer having a ratio of aromatic groups to carbonyl groups

There is illustrated and described a bundle () comprising packaging sleeves () and an outer packaging (), comprising: a plurality of packaging sleeves () of a composite material, and an outer packaging () which surrounds the packaging sleeves (), wherein each packaging sleeve () has a front side () and a rear side (), wherein the front side () and the rear side () of each packaging sleeve () are separated from each other by means of folding edges (F), along which the packaging sleeve () is folded flat, wherein each packaging sleeve () has two openings which are arranged on opposite sides of the packaging sleeve (), and wherein each packaging sleeve () has a longitudinal seam () which connects two edges of the composite material to form a circumferential packaging sleeve (). In order to enable a space-saving, cost-effective and reliable transport of packaging sleeves (), it is proposed that the outer packaging () be produced from a plastics material film ().
