Beschreibung
Zusammenfassung:	Multilayer articles include a fibrous web and a barrier film directly bonded to the fibrous web; wherein the fibrous web includes fibers that include natural fibers, synthetic fibers, or combinations thereof; wherein the synthetic fibers comprise a synthetic thermoplastic polymer selected from an aliphatic polyester, an aromatic polyester, a polyamide, and combinations thereof; and wherein the barrier film includes a thermoplastic aliphatic polyester, a polyvinyl alkanoate polymer having a Tg of no greater than 70C; and a non-lactide plasticizer having an acid number of no greater than 10 and having a weight average molecular weight of no greater than 5000 g/mol. L'invention concerne des articles multicouches qui comprennent une bande fibreuse et un film barrière directement lié à la bande fibreuse. La bande fibreuse comprend des fibres qui comprennent des fibres naturelles, des fibres synthétiques, ou leurs combinaisons, les fibres synthétiques comportant un polymère thermoplastique synthétique choisi parmi un polyester aliphatique, un polyester aromatique, un polyamide et leurs combinaisons, le film barrière comportant un polyester aliphatique thermoplastique, un polymère d'alcanoate de polyvinyle, ayant une (Tg) inférieure ou égale à 70 °C, et un plastifiant non-lactide ayant un indice d'acide inférieur ou égal à 10 et un poids moléculaire moyen en poids inférieur ou égal à 5 000 g/mol.
