摘要

A non-foil packaging laminate for liquid food packaging comprises a first layer of paper situated towards the inner side of the packaging laminate and a second layer of paper situated towards the outer side of the packaging laminate, with the first and second paper layers laminated to each other by a first intermediate bonding layer in a sandwich structure. The packaging laminate further comprises a gas barrier coating layer, coated onto the inner side of the first paper layer by liquid film coating of a liquid gas barrier composition onto the first paper layer and subsequent drying, the liquid composition containing a polymer binder dispersed or dissolved in an aqueous or solvent medium, and a further barrier layer towards water vapour laminated and bonded to the barrier-coated inside of the first paper layer. Also disclosed is a method for manufacturing the laminate, and a packaging container made from the laminate.
