The goal of the research was the investigation of printability of thin plastic plates, produced from the 100% recycled polypropylene, 100% recycled low-density polyethylene and 100% recycled high-density polyethylene chips, made from the separatelly colected waste packaging. The surface roughness, coefficient of friction, surface energy and chemical composition of polymeric plate surface were analysed. Polymeric plates were printed with the UV inks and the quality of prints was determined. The best printability and quality of prints were obtained for PP.

COBISS.SI-ID: 2154608The goal of the research was the determination of the properties of polymeric materials, made from the virgin and recycled polymers, low-density polyethylene and high-density polyethylene. Mechanical properties of plates were correlated with some structural characteristics: softening and melting point, melting enthalpy and crystallinity degree. The comparison of mechanical, structural and surface properties of plates made out of virgin polymers and out of recycled polymers has shown how the recycling process influences the structure and properties of polymeric packaging materials.
