Rational choice and the use of appropriate packaging materials and types of packaging influence the preservation of the qualitative characteristics of the product as well as on the sustainability of the packaged content [1]. Based on testing the thicknesses of different types of materials, it is possible to make the right choice for packaging certain food products. One of the important properties of packaging materials is its thickness. The thickness determines the physical - mechanical as well as the protective properties of the packaging material, and the uniformity of the thickness is important for the passage of material on the packers and the correctness of the formation of packaging units. Quality control of five types of packaging materials was carried out exclusively by measuring their thickness. The results of measurements are shown in this paper. Reducing the thickness, and therefore the mass per unit, is achieved by using these modern polymer materials. In this way, we achieve the savings of packaging material, which is justified from the economic point of view, but also from the ecological point of view.
