Sažetak
This paper investigated the mechanical properties of paperboards (GD2, grammage: 230 g/m2, 280g/m2 and 350 g/m2) with biodegradable polymer coating (polycaprolaton) in order to improve the properties of the material. Polycaprolactone (PCL) coating is further modified by the addition of nanoparticles of alumina (Al2O3), silicon dioxide (SiO2) and zinc oxide (ZnO). The investigated mechanical properties were tensile strength, tensile elongation, bending resistance, double folding resistance, and burst resistance and abrasion test. Prepared samples of coated paperboards were exposed to accelerated degradation (120h). During this time every 24h, colorimetric properties were measured to examine the lightfastness of the print. The study proved that the mechanical properties of the coated paperboard were not impaired. Results of tensile strength, tensile elongation, bending resistance, double folding resistance, and burst resistance point to a minor improvement of paperboard properties. There is an evident increase of abrasion resistance thereby achieving better protection of the print. All samples with nanoparticles have achieved a certain increase of lightfastness.
