METHOD OF MANUFACTURE OF THE LAMINATED PAPER OF THE HIGH DENSITY AND WITH THE HIGH OXYGEN PERMEABILITY AND THE PAPER OF THE HIGH-DENSITY PRODUCED BY THIS METHOD Russian patent published in 2007 - IPC B32B27/10 B65D65/40 D21H27/10 

FIELD: pulp-and-paper industry; methods of production of the laminated paper of the high density and the high oxygen permeability.

SUBSTANCE: the invention is pertaining to the field of the pulp-and-paper industry, in particular, to the barrier substance and the method of its realization. The method allows to produce the laminate of the paper coated with the polyolefin, at that the paper is manufactured out of the wet fibrous mass, which is not enabled to dry before manufacture of the paper, and before the polyolefin application on the paper - the paper is modified in such a manner that its surface energy has changed approximately up to the value equal to the surface energy value of the polyolefin. The presented method ensures the manufacture of the barrier substance with the stable quality and the good barrier properties with respect to the gas and may be used for packaging, in particular, for the food products.

EFFECT: the invention ensures the manufacture of the barrier substance with the stable quality and the good barrier properties with respect to the gas and may be used for packaging, in particular, for the food products.
