PCT No. PCT/SE96/00079 Sec. 371 Date Oct. 10, 1997 Sec. 102(e) Date Oct. 10, 1997 PCT Filed Jan. 25, 1996 PCT Pub. No. WO96/28609 PCT Pub. Date Sep. 19, 1996The present invention relates to coated paperboard for formed articles, which paperboard consists of a fibermatrix in one, two or more layers and a coating and has adequate surface for printing and adequate surface gloss for each specific type of formed articles. The paperboard has been calendered after coating with a heatable calender having a soft extended nip, and has reduced density and reduced grammage at a given value for bending force compared to corresponding coated paperboard which has been calendered before or during and after coating with a heatable or non-heatable calender having a hard or soft nip. Additionally, a production line for the production of such coated paperboard, a process for the production of such coated paperboard, and a method of reducing the susceptibility to crack formation at folding of such a coated paperboard, are described. |
