Beschreibung
Zusammenfassung:	The objective of the present invention is to provide a gas-barrier composite film making it possible to provide a vacuum insulation material that can be used in locations exposed to high temperature. The gas-barrier composite film includes a gas-barrier layer and a polypropylene film layer, and the amount of volatile gas is 6 mg/m2 or less. La présente invention a pour but de proposer un film composite barrière contre les gaz rendant possible de fournir une matière d'isolation sous vide qui peut être utilisée dans des emplacements exposés à une température élevée. Le film composite de barrière contre les gaz comprend une couche de barrière contre les gaz et une couche de film de polypropylène et la quantité de gaz volatile est de 6 mg/m2 ou moins.
