The invention relates to an application system for water-based adhesives to produce corrugated and laminated board products using less adhesive than traditionally possible. The water based colloidal adhesive is selected from the group consisting of biopolymer nanoparticles and formulations based thereon, polyvinyl acetate and formulations based thereon, polyvinyl alcohol blends and formulations based thereon, dextrins and formulations based thereon, polyacrylics and formulations based thereon, vinyl acetate-acrylic copolymers and formulations based thereon, ethylene-vinyl acetate copolymers and formulations based thereon, vinyl acetate-ethylene copolymers and formulations based thereon, and other adhesives of similar characteristics, and blends of any of the former.

L'invention concerne un système d'application d'adhésifs à base d'eau permettant d'obtenir des produits en carton ondulé et contrecollé en utilisant moins d'adhésif que dans les systèmes classiques. L'adhésif colloïdal à base d'eau est sélectionné dans le groupe formé de nanoparticules biopolymériques et des formulations associées, d'acétate de polyvinyle et des formulations associées, de mélanges d'acétate de polyvinyle et des formulations associées, de dextrines et des formulations associées, de polyacryliques et des formulations associées, de copolymères acétate de vinyle-acrylique et des formulations associées, de copolymères éthylène-acétate de vinyle et des formulations associées, de copolymères acétate de vinyle-éthylène et des formulations associées, et d'autres adhésifs aux caractéristiques semblables, et des mélanges de ceux-ci.
