| description | Multi-layered films and methods of manufacturing the multi-layered films are provided. In one aspect, disclosed herein is a method for producing a multi-layered film, the method comprising: co-extruding a gas-barrier material and elastomeric material to form a multi-layered film having a core region that comprises at least 40 gas-barrier layers each comprising the gas-barrier material and each having an average thickness ranging from about 0.5 micrometers to about 2 micrometers; and a plurality of elastomeric layers alternating with the gas-barrier layers, wherein each of the elastomeric layers of the plurality comprises the elastomeric material and each has an average thickness ranging from about 2 micrometers to about 8 micrometers.
L'invention concerne des films multicouches et des procédés de fabrication desdits films multicouches. Selon un aspect de l'invention, l'invention concerne un procédé de production d'un film multicouche, le procédé comprenant : la co-extrusion d'un matériau barrière aux gaz et d'un matériau élastomère pour former un film multicouche ayant une région centrale qui comprend au moins 40 couches barrières aux gaz comprenant chacune le matériau barrière aux gaz et ayant chacune une épaisseur moyenne allant d'environ 0,5 micromètres à environ 2 micromètres ; et une pluralité de couches élastomères alternant avec les couches barrières aux gaz, chacune des couches élastomères de la pluralité comprenant le matériau élastomère et ayant chacune une épaisseur moyenne allant d'environ 2 micromètres à environ 8 micromètres. |
