Abstract
A process for manufacturing a material from a greaseproof paper used as support. At least one face of the support is coated with water or at least one aqueous solution. The support thus becomes a pliable support, The surface of the pliable support is treated by depositing one or more pigmented layers on the surface. This treatment improves the qualities of metallization or of printing or of both of the paper, relative to uncoated greaseproof paper. The pliable support thus becomes a pliable coated support. The pliable coated support is then calendared.
