A novel, eco-friendly, and biocompatible method was applied to form silver nanoparticles (AgNPs) in great water dock (Lapathi radix) (KB) and pu-erh (Camellia sinensis) (PE) extracts. The surface plasma resonance peak of green synthesized AgNPs at 451.8 nm for AgNPs+KB and 440.8 nm for AgNPs+PE was observed via spectral analysis of UV absorbance. In this study, double-layered biopolymer films (FUR/CHIT+HGEL) with AgNPs incorporated in KB solution (AgNPs+KB) and AgNPs in PE solution (AgNPs+PE), were successfully prepared using the casting method. The SEM, XRD, zeta potential and size analyses confirmed the presence of AgNP in the films. The addition of AgNPs in plant extracts improved antimicrobial and antioxidant activity and thermal stability, whereas WVTR experienced a decrease. The nanocomposite films’ orange-brown colour may aid in the protection of food products against UV rays. The composite films demonstrated antibacterial activity against food-borne pathogens and may offer potential in food packaging applications.

The food packaging industry trends refl ect the identi fi ed needs and requirements of consumers because entrepreneurs should sati sfy changing consumer requirements to achieve and maintain a competi ti ve advantage due to innovati on. In the group of socioeconomic needs, the most important ones are lifestyle changes, improving the quality of life through the added value off ered to consumers through packaged products, profi table companies in the sector, packaged product safety and environmental protecti on. The main aim of the study was exploring the validity of food packaging requirements concerning the sati sfacti on of consumer needs. The resulti ng hierarchy of important needs and requirements represents the foundati on for soluti ons and strategies to improve the quality of a consumer's life. Analysis of the results clearly shows that among all socioeconomic needs and requirements posed to food packaging, safety is the most criti cal need for consumers. Other packaging properti es such as convenience and legal requirements fulfi llment are important. Proposed model packaging, which will strati fy consumers' needs and requirements and will help to improve their quality of life, should be characterized by health, simplicity, identi ty, aestheti cs, and meaning. The packaging industry is a branch considered to have high potenti al in the fi eld of applying innovati ve soluti ons. This is mainly related to the desire of introducing soluti ons in the areas of improving safety, functi onality, communicati on and environmental protecti on. Identi fi cati on and understanding of consumer needs is a valuable source of informati on useful
