Controlled release of active compounds from antimicrobial films intented for food packaging applications

Bacterial growth during storage of food is a problem that may be addressed with packaging materials that release antimicrobials during food contact. The controlled release of these active compounds was usually obtained by cross-linked monolayer films but recently, multilayer systems were used to slow down their release kinetics. The aim of this work was to compare monolayer and multilayer films to control the release of two different antimicrobial agents.
