PURPOSE: A multi-layer structure, and a tank consisting of the structure, which has a barrier layer in direct with the fluid contained are provided to improve barrier properties, and to be effectively used in various objects such as, for example, petrol tanks for motor vehicles. CONSTITUTION: The multi-layer structure comprises, successively, a first layer of high density polyethylene(HDPE), a layer of binder, a second layer of EVOH or of a mixture based on EVOH, optionally a third layer of polyamide(A) or of a mixture of polyamide(A) and polyolefin(B). Devices for transferring or storing fluids and more particularly tubes, tanks, chutes, bottles and containers consists of the structure, and its barrier layer(the second or the combination of the second and the third layer) is in direct contact with the fluid contained or transported. 본 발명은 하기 층들로 연속적으로 구성되는 구조물에 관한 것이다 : ·고밀도 폴리에틸렌 (HDPE) 의 제 1 층, ·결합제층 ·EVOH 또는 EVOH 기재의 혼합물의 제 2 층, ·임의로, 폴리아미드 (A) 또는 폴리아미드 (A) 와 폴리올레핀 (B) 의 혼합물의 제 3 층. 또한, 본 발명은 상기 구조물로 구성되며, 차단제층 (제 2 층 또는 제 2 층과 제 3 층의 조합층) 이 함유 또는 이송 유체와 직접 접촉하는, 유체의 이송 또는 저장 장치, 더욱 구체적으로는 튜브, 탱크, 슈트 (chute), 병 및 용기에 관한 것이다.
