Patent

CA 2503966

The present invention relates to a process of manufacturing a high bulk, low weight paper product produced by using a high level of groundwood containing sheet, blade coating with specifically formulated coatings then passing the paper web between two extended-nip calenders, one calender for each side of paper. As a result, densification of the resulting coated paper product is reduced, while maintaining stiffness and opacity comparable to heavier weight sheets.

La présente invention se rapporte à un procédé de fabrication d'un produit en papier léger et bouffant obtenu à l'aide d'un niveau élevé d'une feuille de pâte mécanique, par couchage à la lame avec des couchages formulés spécifiquement, puis par le passage d'une feuille de papier continue entre deux calandres à ligne de contact étendue, une calandre pour chaque côté de papier. Ainsi, la densification du produit en papier couché obtenu est réduite, alors que la rigidité et l'opacité sont comparables à des feuilles plus lourdes.
