Use of biodegradable polymers and antimicrobial packaging materials in food packaging

The purpose of the article is to analyze the characteristics of polymers that are biodegradable and used in food packaging, to identify the most promising materials for food packaging, as well as to find ways to solve problems associated with the use of this type of packaging. Methodology. Methods of  theoretical  search, system  approach  and  logical  generalization are used. Results. In the article currently available types of packaging materials that are biodegradable are analyzed, their main advantages and disadvantages are identified. These materials are classified on the basis of their chemical composition and methods of synthesis. The most optimal compositions of materials for food packaging are determined, as well as the main methods of improving their functional properties. Particular attention is paid to materials with antimicrobial properties, which should be used as active food packaging. Thus, you can improve the quality of the packaged product, as well as extend its shelf life. Antimicrobial packaging materials based on starch, polylactic acid and polyhydroxybutyrate are considered. Further prospects for research on this topic are identified. Scientific novelty. The main properties of biodegradable polymers and the characteristics of antimicrobial packaging materials based on these polymers, which can be used for food packaging, were analysed. Practical significance. Currently, most food packaging materials do not decompose and create serious environmental problems. Therefore, new technologies are being researched and developed to study the complex interactions between packaging materials and food products. The use of biodegradable polymers can significantly reduce the amount of plastic waste. In addition, the synthesis of biopolymers from renewable resources is cost-effective because it reduces the cost of packaging. Moreover, the use of antimicrobial materials based on biodegradable polymers in food packaging can extend the shelf life of the latter, so the use of these materials can preserve product quality and provide economic benefits.
