Food packaging. Polysaccharide. Protein. Composite Introduction The huge production of plastic waste is associated with low recycling or reuse rates and no sustainable policies that support a circular economy of plastic waste to environment . The food industry uses plastics for packaging singleuse food consumption which has increased substantially in recent decades. With an annual growth rate of 5%, the worldwide packaged food market was valued at $1. 9 trillion in 2020 and is expected to reach $3. 4 trillion by 2030. Food packaging is able to maintain food safety, increase food shelf life, and prevent food waste or loss . In addition, the widespread use of commercial food packaging derived from petroleum-based plastics contributes to the release of chlorofluorocarbons (CFC. into the atmosphere and exacerbates environmental pollution. This issue is further compounded by the fact that such packaging is typically designed for single use and requires up to 1,000 years to degrade. In light of these concerns, the development of edible films as a sustainable alternative to conventional plastic packaging is essential. Edible film is a food wrapping that can improve product quality and shelf life . Because of edible films can improve microbiological and physicochemical stability in low temperature storage . , it can be found in products such as chedar cheese, sausages, candy and fruit.

Biopolymer-based edible film offering some benefits, including consumption safety, economic value, and environmental sustainability . These materials are expected to has mechanical characteristics similar to commercial food packaging. To improve its properties such as flexibility, tensile strength, and resistance to high humidity environments of edible films, plasticizers are used, including glycerol, chitosan, and sorbitol . The selection of the type of plasticizer needs to be considered . The modification of biopolymer-based edible films has the potential to enhance their contribution to the food security Accordingly, this review aims to examine the role of edible films in food packaging and to explore the various types of biopolymers suitable for their production. the biopolymer system functions as a barrier between food that can inhibit the growth of phenomena, hence it has good product quality.

Industry and Economy Biopolymer-based Edible Film The use of biopolymers would increase bioaccessibility of biosynthesis which has an impact on the scattering of plastic waste. The advantages of biopolymers in making edible films as packaging materials can also act as carriers of probiotics, nutraceuticals, flavors, colors, and other additive and bioactive compounds . Therefore, edible film would enhance the nutrition of food products and store mass because Production efficiency and Fast decomposition Environment Waste is reduce Bioshift with Edible Film Innovation and Technology Waste utilization New technology Public Awareness Edible Film Edible film is a thin layer made from environmental friendly materials to coat a product and role as a barrier to prevent moisture loss, then protect food products from degradation and enhance food safety . In addition to controlling moisture, edible film perform as an effective inhibitor against oxygen, which is a major cause of oxidative reactions that can result in discolouration, off flavours, and nutrient loss. One of the advantages of edible film is that it can be consumed along with the packaged product, since it is made from edible materials. Several advantages of using edible film depicted in Fig 1. The addition of antimicrobial agents and plasticizers in the formulation of edible films can also improve their mechanical properties, including tensile strength, compressive strength, biodegradability, and the inhibition of microbial growth that may compromise product quality.
