Title
(EN) BLOWN FILM MATERIALS AND PROCESSES FOR MANUFACTURING THEREOF AND USES THEREOF
(FR) MATÉRIAUX POUR FILMS SOUFFLÉS ET PROCESSUS POUR LEUR FABRICATION ET LEURS UTILISATIONS
Abstract
(EN)
Provided herein are blown films with encapsulated active agents, such as volatile anti-microbial agents, suitable for use as food packaging materials. Also provided herein are methods of manufacturing such blown films. The methods include extruding a bubble from molten polymers, dispensing active agents inside the bubble, and collapsing the bubble such that the bubble self-adheres to form a film with the active agents encapsulated.
(FR)
La présente invention concerne des films soufflés dotés d'agents actifs encapsulés, tels que des agents antimicrobiens volatils, convenant à une utilisation en tant que matériaux d'emballage alimentaire. La présente invention concerne également des procédés de fabrication de tels films soufflés. Les procédés comprennent l'extrusion d'une bulle à partir de polymères fondus, la distribution d'agents actifs à l'intérieur de la bulle, et l'affaissement de la bulle de telle façon que la bulle auto-adhère pour former un film où les agents actifs sont encapsulés.
