Abstract
A multi-layer thermoplastic structure that has at least one layer that is between 0.3 and 20 mm thick and is made of an ethylene-vinyl alcohol copolymer with a density of between 0.94 and 1.4, and a melt flow index of between 1.3 and 4.2 g/10 minutes at a temperature between 170 and 240 degree C. The multi-layer thermoplastic structure is obtained by rotation moulding and is of particular benefit when functioning as a gas tank.
