substitutes for synthetic polymers. The starch-based film is one of the best alternatives; it is a cost-effective material that has been investigated as an excellent raw material for the production of a biodegradable film, additionally, the development of starch-based films for use as antimicrobial packaging or coating is one of the most promising active packaging systems, using aloe vera as an organic antimicrobial agent derived from plants has risen significantly, due to its film-forming properties, antimicrobial properties, and biochemical properties, aloe vera gel has been identified as one of the best biodegradable films, Aloe vera also contributes to the film’s exceptional properties, Starch film, Aloe vera, Antimicrobial properties, Mechanical properties, Thermal properties, Physicochemical properties, Microbial food spoilage occurs primarily on the food’s surface, edible films and coatings are particularly advantageous for microbial contamination control on the ground because they can act as additive carriers and release active compounds onto food surfaces, where they can be used to inhibit microbial growth, edible films and coatings are thin layers of edible materials that can act as a barrier to moisture, gases, and solute movement in food. Due of their superior features including as biocompatibility, edibility, and a wide range of applications, they are excellent alternatives for traditional wrapping materials, primary distinction between coatings and films is that coatings are applied to foods in liquid form, whereas films are molded into sheets and then utilized as wrapping materials. Edible films or coatings make it easier to transport, store, and display fresh and processed foods, to formulate edible films or coatings with functional properties, both the film-forming base materials and the bioactive ingredients must be carefully selected, proteins, polysaccharides, and lipids are the primary base materials used in the manufacture of edible films and coatings, and the choice of a specific material or a combination of different materials, one of the bio active component that has potential in producing edible films and coating is aloe vera (AV aloe vera gel is used in the food industries to produce functional foods, as a natural preservative and as antimicrobial agent material added in edible films and coatings, there are two traditional approaches to developing an effective coating and film formulation: (i) the material science approach and (ii) the application of coating material to the fruit surface, two additional events are included in the material science approach: (i) biopolymer to gel conversion and (ii) gel to thin film formation, these events are interconnected, which emphasizes the importance of considering the application of coating material prior to applying it to the fruit surface, the formulations must be evaluated independently for their film thickness, solubility, moisture content, water vapour (WVP) permeability, oxygen barrier properties, transparency, colour, tensile strength, elongation at break, elastic modulus, and antimicrobial properties, It is also critical to determine the extent to which secondary components such as plasticizers affect thermal (gelatinization) and postthermal (retro-gradation) events in starch-based edible film formulations. These occurrences are necessary for the formation of a film or coating because they take advantage of the starch unit is intermolecular associations-dissociations, plasticizers, water, and co-biopolymers all have a significant effect on the thermal actions (granule swelling, amylose or amylopectin chain disintegration, and glass transition) of the film, demonstrating their influence on the overall film properties, starch is inexpensive, widely available and can be used to make edible films for food applications due to their low oxygen permeability, corn starch has excellent film-forming properties as a result of its high amylose content and can thus be used in the development of films, according to recent research, adding plasticizing agents and other active ingredients to starch polymers could further enhance their properties in water barriers. Plasticizers are critical ingredients in the production of edible films and coatings because they increase the versatility and toughness of polymers, polyols (for example, glycerol and mannitol) were previously described as the most starch-compatible plasticizers, starch-based films infused with AV. The use of AV gel as an antimicrobial agent and AV rind as reinforcement in starch-based films.
