FIELD: packaging.

SUBSTANCE: invention relates to the manufacture of packaging material. The method includes steps in which a layer (1) of the core material is provided from a fiber-based material having an inner side (3) and an outer side (5). The layer (1) of the core material is embossed to form

embossed elements (10) having an initial height (d1). The embossed elements (10) protrude from the outside (5) of the said layer (1) of the core material for subsequent formation of a tactile pattern on the side of the packaging (40), which is to be formed by the said packaging material (20). At least one layer (24) is laminated on the inner side (3) of the said embossed layer (1) of the core material, so that the height of the embossed elements (10) is temporarily reduced to a minimum height (d2).

EFFECT: invention is aimed at ensuring the integrity of the inner layers of the laminate in the manufacture of packaging material.
