Zusammenfassung:	A compostable multilayer film as well as hermetically packaged products using said compostable multilayer film. The compostable multilayer film includes a first film located on a first exterior surface (i.e., exterior of the package) the first film being selected from a PLA film, a paper, and a starch based film; a second film located on a second exterior surface (i.e., the interior of the package, contacting the product) the second film comprising a blend of PLA and PBAT; and a barrier film located between the first film and the second film. The barrier film including a barrier layer and a base film having at least a compostable layer, a delamination layer, and a support layer, wherein the delamination layer and the support layer are removed from the barrier film prior to inclusion in the compostable multilayer film. The compostable multilayer film may be suitable for extended shelf-life storage of fluid products. Film multicouche compostable et produits emballés hermétiquement utilisant ledit film multicouche compostable. Le film multicouche compostable comprend un premier film situé sur une première surface extérieure (c'est-à-dire, l'extérieur de l'emballage), le premier film étant choisi parmi un film PLA, un papier et un film à base d'amidon ; un deuxième film situé sur une seconde surface extérieure (c'est-à-dire l'intérieur de l'emballage, entrant en contact avec le produit), le deuxième film comprenant un mélange de PLA et de PBAT ; et un film barrière situé entre le premier film et le deuxième film. Le film barrière comprend une couche barrière et un film de base ayant au moins une couche compostable, une couche de délaminage et une couche de support, la couche de délaminage et la couche de support étant retirées du film barrière avant l'inclusion dans le film multicouche compostable. Le film multicouche compostable peut être approprié pour un stockage à durée de conservation prolongée de produits liquides.
