Sheet lamination of printed paper material is a widely used finishing method for many different products, for instance folders, book covers, board games, jigsaw puzzles or display packaging. Laminated cardboards made of a corrugated cardboard base and laminated with printed paper are manufactured on sheet-to-sheet laminators with a laminating section and a delivery section. In the lamination process, different materials with a high-quality pre-printed surface are bonded to a cardboard or corrugated cardboard substrate. A gluing unit applies the adhesive to the flute tips (open flute) or the top layer of the carrier substrate and aligns it with the printed top sheet. In the final step, the substrates are then bonded together. The adhesive has to meet special requirements: facilitate clean processing on roller applicators, no foaming, no odour, and excellent flatness of the compound – with maximum adhesion.
Placed prominently in retail stores, from supermarkets to pharmacies and petrol stations, eye-catching point-of-sale displays draw the customers’ attention to special offers and product campaigns. Due to the generally limited lifecycle, they must be easy to handle while also providing enough stability for the products showcased in them. Enterprises also have to react spontaneously and fast to new market developments.
Therefore, POS displays need to be manufactured from a sustainable material which can be disposed in an environmentally sensitive way once the promotion has ended. Jowat has developed special dispersion adhesives for this purpose to join the printed papers and the carrier material (in this application, usually corrugated cardboard).
While online games have become increasingly popular among young and old alike, classic board games still hold a strong appeal to game lovers.
Board games are also manufactured by laminating a carrier substrate with a pre-printed paper. To ensure the highest quality possible in this process, Jowat has developed special Jowacoll® dispersion adhesives that withstand the high stress to which the material is exposed. Glues from the Jowacoll® series also facilitate superior results in the manufacture of folders.
Jowat has many years of experience in bonding all types of papers and cardboards – whether on highly absorbent greyboard, in the overlapping area, paper with plastic content or printed with digital printing inks. The dispersion adhesives, crosslinking agents and cleaners by Jowat are perfectly adapted to each other and meet all individual requirements: excellent adhesion, no wave structures, and optimum LayFlat properties.
