Society's interest in natural and clean products in many areas, such as food and cosmetics, has increased considerably. It has led to the development of new techniques in the packaging of products so that the wastes from the preferred products can be recycled. In this context, Pinus brutia bark was preferred within the scope of the study to transform natural wastes into functional components and use them as packaging material. P. brutia bark (PBB) samples were collected from Bursa, Turkey. PBB samples were ultrasonically extracted using various solvents (acetone, butanol, ethanol, ethyl acetate, hexane, methanol, petroleum ether, and water) and a solvent‐acidic hydrolysis system. The phenolic content profile of PBB samples was determined using high‐performance liquid chromatography with diode‐array detection, and total flavonoid content, antioxidant capacity, and total phenolic content were determined. Chitosan‐polyvinyl alcohol (CS‐PVA) films loaded with polysaccharides and containing methanolic extract were developed. The physical, chemical, and mechanical properties of the films were characterized. It is known that the thickness of the films determines the mechanical properties required to maintain the integrity of the packaging during storage and transport. From the results of the study, it was concluded that the elongation at break value was higher in CS‐PVA‐PBB‐M films (111.08% ± 10.46%), Young's modulus (31.74 ± 21.37 N/mm2), and tensile strength (3.01 ± 0.50 N/mm2) values were higher in CS‐PVA films. In this case, it was concluded that adding proanthocyanidin to edible films gives flexibility to the films.
