Edible packaging has been a topic of much discussion during recent years, mainly due to its lower environmental impact. This study aimed to investigate the properties of an edible packaging made from a combination of carrageenan, orange essential oil (OEO), and trehalose (Tre) under different humidity conditions. The films were analyzed based on their water content, solubility, and textural properties, such as strength and breaking strain. The results of the study showed that the addition of trehalose reduced the water content and increased the strength of the packaging, regardless of the humidity conditions. The inclusion of orange essential oil also contributed to lower water content, which led to more water-resistant packaging (during standard humidity conditions (45%)-c: 15.31%; Tre3OT80: 4.04%, Tre1OT80: 4.48%). The findings of this study have important implications for the production of stable and environmentally friendly edible packaging. The results demonstrate the potential of trehalose and orange essential oil as additives to enhance the properties of edible packaging, particularly in terms of its resistance to moisture. The best results were found in Tre1OT80 and Tre3OT80 samples. Moreover, the study emphasizes the importance of considering storage conditions in the development of edible packaging, as different humidity levels can significantly affect the packaging's properties and shelf life. The findings have practical applications for the food industry, particularly in the development of sustainable packaging solutions and for further studies where the application of this packaging can be analyzed for different foodstuffs.

Single use plastics are a leading source of microplastics that have been detected along the food chain. This study evaluated the potential of starch (ST) and carrageenan (CRG) in packaging film formulation. CRG isolated from the seaweed (SW) was blended with starch and cast to obtain films whose moisture content (MC), total soluble matter (TSM), degree of solubility (DS), water vapor permeability (WVP), opacity (O), contact angles (CA), moisture absorption (MA), and percent elongation (PE) were evaluated.
