Abstract:

The main types of interactions of packaged food product and packaging are analyzed. These interactions may occur between the polymer film packaging material and the product. It is found that the most simple to implement an insilation of internal space of polymer film packaging from environmental impact. It is noted that the permeability of gases and gas mixtures through nonporous film polymer packaging is typically considered within the «dissolution – diffusion» mechanism. Usually the study of these processes requires special equipment. The main factors that affect the permeability of the polymer film packaging material are analyzed. It is noted that the permeability of the multilayer polymeric film materials is dependent on the physical and chemical properties of the components and process parameters. The main parameters are: temperature, pressure and concentration of the substance. It is noted that molecular interactions with packaging materials can be classified into the following types: permeability of compounds through the polymer film packaging; sorption of compounds by polymer film packaging and migration of compounds from a polymer film packaging. It is indicated that obtained results may be used for the design of packaging film materials with the necessary and stable barrier properties. The technique of experimental studies of the barrier properties of various polymer film packaging materials and absorption capacity of packaged products is proposed and its results are described. This technique is realized using available equipment. The dynamics of moisture penetration inside the packaging is investigated. It is found that the absorption capacity of silica gel remained stable for 15-20 days from the beginning of the experiment. The highest moisture permeability has an ethylene and vinyl acetate copolymer and low-density polyethylene, and the lowest – polypropylene Author Biographies Олександр Євгенович Колосов, National Technical University of Ukraine «Igor Sikorsky Kyiv Polytechnic Institute», Pobedy Prospect, 37, Kyiv, Ukraine, 03057 Doctor of Technical Sciences, Professor, Senior Researcher, Member of theAcademyofSciencesof Higher Education ofUkraine, Ukrainian Patent Attorney Department of Chemical, Polymeric and Silicate Machine Building
