Beschreibung
Zusammenfassung:	A multi-layer laminate hose having a fluorocopolymer layer and a polyamide resin layer directly laminated thereto, wherein the fluorocopolymer comprises (A) polymerized units of tetrafluoroethylene, (B) polymerized units of ethylene and (C) polymerized units of itaconic anhydride or citraconic anhydride, in which the molar ratio of (A)/(B) is from 20/80 to 80/20, and the molar ratio of (C)/((A)+(B)) is from 1/10000 to 5/100, and which has a volume flow rate of from 1 to 1000 mm /sec. The multi-layer laminate hose is excellent in the fuel barrier properties.
