SUSTAINABLE DYNAMIC POLYMER NETWORKS FOR PACKAGING: DEVELOPMENT AND PROSPECTS OF BIO-BASED VITRIMERS

Abstract

Abstract. Introduction. The development of biodegradable and recyclable polymer materials is a key priority in the context of the global environmental crisis and the growing accumulation of plastic waste. In recent years, a new class of materials-vitrimers-have been attracting significant interest due to their unique combination of thermoset-like mechanical strength and reprocess ability enabled by dynamic covalent bonding. Objective of the study. This review article presents current approaches to the synthesis and application of bio-based vitrimers, primarily derived from epoxidized vegetable oils (EVO). Results and Discussion. Chemical strategies for creating polymer networks are studied in detail, including transesterification mechanisms, catalyst selection, and crosslink density control. The potential for structural modification using natural additives such as cellulose and lignin is discussed with the aim of enhancing mechanical, barrier, and antioxidant properties. Particular attention is given to the functional performance of these materials, including thermal resistance, moisture stability, mechanical robustness, self-healing capacity, and biodegradability. Recent research highlights the potential of bio-based vitrimers for practical implementation as packaging materials for various applications, including food, pharmaceutical, and active packaging systems with biofunctional barrier properties. Conclusions. Special emphasis is placed on the scalability of synthesis processes, durability under real-world conditions, and environmental safety.
