CA 2452121

In order to provide grease, oil and wax resistance to a paper substrate, a coating containing a binder, a filler material and calcium carbonate is used. The coating of the invention is essentially free from fluorocarbons, which are considered harmful to human and animal populations, and surfactants and other chemicals which may alter the color of the coated paper. The coated paper has a GE brightness level between approximately 50 and approximately 90, while providing superior grease, oil and wax resistance.

Cette invention concerne un revêtement renfermant un liant, un matériau de charge et du carbonante de calcium qui rend un substrat papier résistant à l'action de la graisse, de l'huile et de la cire. Ce revêtement est essentiellement exempt de fluorocarbures, jugés nocifs pour l'homme et l'animal, ainsi que de tensioactifs et autres produits chimiques pouvant altérer la couleur du papier enduit. Le papier enduit possède un degré de blancheur GE compris entre 50 et 90 environ, ce qui lui confère une résistance supérieure à la graisse, à l'huile et à la cire.
