Edible and Oral Thin Films: Formulation, Properties, Functions, and Application in Food Packaging and Pharmaceutical Industry

Abstract

Edible and oral films are the directly consumable materials in the form of food packaging or a drug dosage. The edible oral films are developed using edible biopolymers and food grade additives. The packaging application of film provides good barrier properties to the food and thus enhances the overall quality and safety of a food product. In pharmaceutical application, these films proved as an effective form of drug administration as they disintegrate and dissolve instantly when come in contact with saliva. Thus, these films can provide antioxidant and antimicrobial properties, extend shelf life of a product, and can provide better delivery of active ingredients. These advantages of the edible oral film have paved its growth in both the food and pharmaceutical industries. This chapter will discuss the components of the film and their selection, method of the formulation, film properties and effect of different components on film, and finally the application of these films in the food and pharmaceutical industries.
