Title (EN) A PACKAGING MATERIAL AND METHOD OF PREPARATION THEREOF
(FR) MATÉRIAU D'EMBALLAGE ET SON PROCÉDÉ DE PRÉPARATION
Abstract:
(EN) A packaging material is provided. The packaging material comprises a degradable polymer (e.g. poly(ε-caprolactone)) and a natural antimicrobial agent (e.g. chitosan), wherein the degradable polymer forms a polymeric matrix within which the natural antimicrobial agent is dispersed. A method of preparing a packaging material, and use of the packaging material in food packaging are also provided.
(FR) L’invention concerne un matériau d'emballage. Le matériau d'emballage comprend un polymère dégradable (par exemple, du poly (ε-caprolactone)) et un agent antimicrobien naturel (par exemple, du chitosane), le polymère dégradable formant une matrice polymère dans laquelle l'agent antimicrobien naturel est dispersé. L'invention concerne également un procédé de préparation d'un matériau d'emballage, et l'utilisation du matériau d'emballage dans un emballage alimentaire.
