ABSTRACT
Introduction:
The global production of containers and packaging is the largest area of processing synthetic plastics (about 40%), the production volumes of which exceeded 400 million tons per year. The service life of many types of packaging is calculated on several days. Used packaging and its waste replenish the content of landfills, pollute natural ecosystems and the waters of the world ocean. The accumulation of plastic waste, primarily due to giant waste of plastic packaging, has become a global environmental problem. A relevant and highly sought-after direction is the transition to degradable packaging and the search for affordable polymeric materials for this. The aim of this study was to obtain and characterize degradable film packaging for food products.
Methods:
Single-layer films were obtained by flat-slot extrusion of polymer melt using a Brabender laboratory extruder. Comprehensive studies of surface properties (SEM, AFM, measurement of contact angles), mechanical strength (Young's modulus, elongation at break), sanitary and chemical studies, resistance to model liquids and typical microflora of meat and dairy products were carried out taking into account current international standards.
Results:
The technology of extrusion production of smooth films from poly-3-hydroxybutyrate melts synthesized using WFO as a carbon substrate has been developed and implemented. The physical and mechanical properties of the polymer during melting and extrusion, the structure and characteristics of the film surface, moisture and vapor permeability, resistance to the effects of model liquid media simulating food products, and antibacterial activity against the test microflora of meat and dairy products (Bacillus subtilis, Micrococcus luteus, Pseudomonas fluorescens) in forced contamination tests have been studied.
Conclusion:
Comprehensive studies have shown that the obtained samples of degradable film products meet the indicators of food packaging, according to the requirements of current international ISO standards.
