CA 2596662

A high strength film/board lamination is formed from a cross-oriented laminated film and a corrugated layer. The cross-laminated film is formed from a first oriented plastic layer and a second oriented plastic layer in which the orientations of the plastic layers cross at an angle between but not equal to zero degrees and 180 degrees relative to one another. The cross-oriented laminated film is adhered to the corrugated layer in a noncontinuous manner. A method of forming a high strength lamination and a method of improving tear resistance in corrugated paper or paperboard based materials are also disclosed.

L'invention concerne une stratification de film/panneau à haute résistance formée à partir d'un film stratifié croisé et d'une couche ondulée. Le film stratifié croisé est constitué d'une première couche plastique orientée et d'une seconde couche plastique orientée dans laquelle les orientations des couches plastiques à un angle compris entre 0 et 180 degrés l'une par rapport à l'autre. Le film stratifié croisé est collé à la couche ondulée de manière non continue. L'invention concerne également un procédé permettant de produire une stratification à haute résistance et un procédé permettant de renforcer la résistance à la déchirure dans des matériaux à base de papier ou de carton ondulés.
