FIELD: process engineering.
SUBSTANCE: multilayer material for tubes with integrated aluminium layer. The latter has oriented coextruded protective layer arranged on its both side and boned with aluminium layer via interlayer. Note here that said interlayer facing tube inner side is one-layer structure, preferably, multilayer structure, primarily, one-, two-, three-, four-, or five layer structure. Note also that one to three said layers include, separately or in combination, the material of first, second and third bonding layer. Invention covers the method of producing abode described tube and tube thus made.
EFFECT: improved barrier properties.
