FIELD: packaging industry.
SUBSTANCE: invention relates to a multilayer composite material, in which at least a first layer is connected to a second layer by means of an adhesive agent, wherein the adhesive agent is a mixture of a first curable adhesive and a second non-curable adhesive, and wherein the bending stiffness of the composite material is set to a ratio of the mixture between the two adhesives in range of 50 to 100 mN in the longitudinal direction and from 90 to 120 nM in the transverse direction of the composite, wherein bending stiffness of the composite material drops when more than second non-curable adhesive is added.
EFFECT: excluding rigidity of package made of composite material.
