CA 2194074

Paperboard is coated with a coating containing one or more triglycerides. The coating may also contain a plasticizer. Although the coated paperboard takes up significant amounts of water in humid or cool room conditions, the paperboard exhibits good wet strength properties. The coated paperboard is especially useful to produce boxes.

On applique sur le carton un revêtement contenant un ou plusieurs triglycérides. Le revêtement peut également contenir un plastifiant. Bien que le carton à revêtement absorbe des quantités importantes d'eau dans des conditions ambiantes humides ou froides, il présente de bonnes propriétés de résistance mécanique à l'état humide. Le carton à revêtement est particulièrement utile pour réaliser des boîtes.
