PACKAGING LAMINATED MATERIAL, METHOD FOR PRODUCTION THEREOF AND PACKAGING CONTAINER PRODUCED FROM LAMINATED PACKAGING MATERIAL Russian patent published in 2019 - IPC B65D65/40 B65D85/72 B32B27/32 B32B15/85 B32B7/12 B32B29/00 

FIELD: laminated products or materials.

SUBSTANCE: invention relates to packaging oxygen-sensitive liquid food products and relates to a laminated packaging material, a method for production thereof and a packaging container. Laminated material has a layer of paper or cardboard and a layer acting as a barrier to gas, and consists of material with barrier properties with respect to gases, particularly oxygen. Barrier layer is connected to paper or cardboard layer by means of laminating layer, which includes at least, one layer of adhesive polymer or polymer composition, which contains monomer links with functional groups of carboxylic acid. Laminated packaging material also has external liquid impermeable coatings on both sides of the paper or cardboard layer.

EFFECT: invention enables to create a packaging laminated material having improved integrity/adhesion between the laminated layers, and also provides good integrity to the packaging container made therefrom and a method which enables to obtain and maintain strong bonding of functional groups between the barrier layer with respect to gas and paper or cardboard layer of packaging laminated material and which can be implemented without excessive energy consumption and without using substances which are harmful to health and environment.
