**1. Introduction**

The packaging of foods plays an important role in the preservation of the product throughout the storage and distribution chain. The main purpose of packaging is to protect food from contamination and extend its shelf life [1]. To meet this purpose, packages are produced from different raw materials. Plastic packages are frequently used in food packaging due to their high quality, easy processing, and combination properties. However, today, the harmful effects of plastic waste on the environment have led the food industry to use biodegradable packaging materials [2]. Biodegradable packaging materials are obtained from renewable bio-based resources and are often referred to as "biopolymers" [3]. Biopolymers are strong alternatives to nonbiodegradable and nonrenewable plastic packaging materials due to their environmentally friendly nature [4]. Synthetic films used as packaging materials negatively affect the environment since they are not biodegradable, while biological-based packaging materials obtained from renewable materials draw attention to their biological compatibility, biodegradability, environmental protection, and reliability [3]. Biodegradable polymers are defined as polymers that can be broken down into simple molecules, such as carbon dioxide, methane, water, and inorganic compounds in a certain process in nature as a result of the enzymatic activity of microorganisms [5, 6]. Bioplastics are generally materials that can be produced from renewable resources such as sugar, corn, and potatoes, containing proteins, lipids, and polysaccharides or from certain microorganisms, algae, and fungi [7, 8]. Environmentally friendly biodegradable polymers have good mechanical and barrier properties and are thus seen as potential packaging materials to replace traditional plastic packaging materials [4, 6].
