Laminated packaging combines advantages of corrugated board with those of offset printing. This means stable and light packaging combined with high-quality offset printing can be produced. What the laminating machine actually does is mate a corrugated sheet with a printed sheet. The open corrugated sheet is wetted with water-soluble adhesive on the crest (highest point of a corrugation). The printed sheet is then positioned. The two parts are joined together by the adhesive in the pressing area.
