FIELD: textile, paper.
SUBSTANCE: paper product includes at least two layers. The method includes the following: (i) provision of aqueous suspension that contains cellulose fibres; (ii) adding microfibrillar polysaccharide into suspension in amount sufficient to produce from approximately 0.05 to approximately 50 wt % relative to mass of cellulose fibre; (iii) dehydration of the produced suspension and moulding of the first layer, which has density from approximately 150 to approximately 500 kg/m3, of the specified layer paper product. Also refers to a version of the method for production of a layer paper production, and also to a layer paper product itself (its versions) and to application of a layer paper product.
EFFECT: improved ability to bind fibres in at least one inner layer of a paper product, improved resistance to product bends, higher compression strength, resistance to lacing, bend, Z-strength, stiffness index, compression strength in case of lower density of a paper product.
