Combined materials include products consisting of different layers: polymer films, paper, foil, and fabric. Combined materials are widely used as electroinsulating and packing materials. The materials are widely used as their characteristics can vary due to composition choice, alternation of layers, level of adhesion between the layers, choice of best available technology and equipment to achieve the required material.
The alternation of layers, i.e. material structure is determined by its functions.
The main ways of the materials production: lamination, coextrusion, extrusion laminating, and combing of paper. These ways differ by the type of the adjoining layer.
