Research activity

  • Packaging
  • Packaging and materials sustainability and circularity
  • Coatings
  • Bio-degradable polymers
  • Bio adhesives
  • Material analysis

Research on structural properties and applications of natural, bio-polymers and fibers: research on the structure and properties of polysaccharides, proteins, starches, waxes, lignin and other biomaterials and bio wastes used for coatings on paper, cardboard and packaging materials. Research is also related to the production of films / foils that can be used for wrapping food products. Research has been carried out and is still ongoing within COST actions CA 15118 (FoodMC) and FP1405 (ActinPak), CA17128 (LignoCOST), CA18125 (Aerogel), CA19124 (CIRCUL-A-BILITY). The results were published in SCI articles and conferences.

Research of natural, bio-polymers, used as adhesives in the packaging industry: polysaccharides, starches and waxes research that could be used in packaging materials. Research is carried out under the COST action CA15216 (ENBA). The results of the research are published in SCI magazines and conferences.

Research of treatment procedures of coating solutions using various technologies: the use of ultrasonic technology, a bath, which makes it possible to improve the homogeneity of the coating and films from these natural polymers. The results of the research were published in SCI magazines.

Research of the printing properties of coated papers: research of the printing properties of coated paper with bio polymers. The results of the research were published in SCI magazines and conferences.

Research of the resistance of packaging materials and the search for solutions to insect infections, within the COST action CA151118 (FoodMC).

Research of the packaging sustainability, circular economy within collaboration with University of North Texas, USA (published articles).
