Physical Evaluation of Biodegradable Films of Calcium Alginate Plasticized with Polyols

The influence of different polyols as plasticizers of alginate films on their physical attributes like moisture content, soluble mass in water, water uptake, water vapor permeability, opacity and mechanical properties were determined and the results discussed based on scanning electron microscopy observations and glass transition temperature. The alginate films were obtained by casting, using t...

Effect of Different Formulations on Mechanical and Physical Properties of Calcium Alginate Edible Films

Background: Environmental problems of the plastic materials used in food packaging and the demand for food quality improvements lead to the development of packaging in natural materials. Edible films such as calcium alginate extend the shelf life by acting as a selective barrier against moisture and oxygen. The main objective of this study was to explore a calcium alginate based edible film to ...

Properties of Biodegradable Multilayer Films Based on Plasticized Wheat Starch

Over the last decades, there has been growing needs to find alternatives to petroleum-based products because of environmental concerns. Starch is an inherently biodegradable, renewable and low-cost material, and has high potential in food or non-food applications [1]. In that respect, the applications of starch have given rise to a great number of studies [2–5]. Native starch, when plasticized ...
