DESIGN AND CHARACTERIZATION OF ACTIVE BILAYER COATING FOR CHEESE PACKAGING WITH IMPROVED FUNCTIONAL PROPERTIES
In addition to potentially resolving environmental issues that come from plastic and food waste, active biodegradable packaging is being developed to increase the shelf life, quality, and safety of packaged food. In order to overcome the drawbacks of monolayer hydrocolloid-based coating, such as poor mechanical and barrier properties, the des...

OPTIMISATION OF THE APPLICATIVE PROPERTIES OF BIODEGRADABLE CELLULOSE ACETATE-BASED FILMS USING THE PRINCIPLES OF GREEN CHEMISTRY
There is a growing interest in the use of biopolymers for obtaining biodegradable packaging with the addition of green components. The aim of this paper is to develop films based on cellulose acetate and polycaprolactone-diol intended for active packaging by adding biocompatible plasticizers. The films were obtained by solution casting method...
