The protective coatings and flexible packaging industries play a pivotal role in modern society. They contribute to human health, safety, comfort, and economic progress. Initially, these materials were produced from naturally occurring components; however, they have since evolved into intricate compositions designed to fulfill various performance criteria.  Currently, the majority of these materials are discarded in landfills, and their carbon content cannot be recovered or reused efficiently. In recent years, database statistics show a steady increase in research related to functional coatings, reflecting the growing interest in innovative and sustainable solutions. The global focus on reducing reliance on fossil fuel products and mitigating environmental impacts is accelerating efforts to integrate renewable resources into coating technologies. These technologies utilize bio-based raw materials, including biopolymers and natural oils, as well as biodegradable materials derived from microorganisms, plants, and animals. To address environmental concerns, leading coatings and packaging manufacturers have launched scientific and technical research to improve the sustainability of their products. Ongoing research focuses on the development of bio-derived materials, the adoption of energy-efficient manufacturing processes, the design of long-lasting products, and the use of sustainable and renewable resources. In addition, companies seek financial and competitive advantages through proactive internal initiatives. This highlights the urgent need for a circular economy model that overcomes current limitations in recycling and decomposition technologies. The authors stress the significance of comprehending society's tendency to prioritize and value sustainability, along with the financial and competitive advantages that may result from adopting proactive in-house efforts.
