MULTI-LAYER LAMINATE FOR TUBES WITH AN EMBEDDED BARRIER LAYER AND TUBE PRODUCED THEREFROM AND USE OF SUCH A LAMINATE

摘要

The invention relates to a multi-layer laminate for tubes with an embedded barrier layer (50), the laminate having an outer cover layer (30a) delimiting the laminate on one side, and an inner cover layer (30i) delimiting the laminate on the other side, between which cover layers the barrier layer (50) is disposed, the laminate having an asymmetrical structure in relation to the barrier layer (50), particularly in respect of the cover layers (30a, 30i), wherein, in particular a molecular orientation of the inner cover layer (30i) differs from a molecular orientation of the outer cover layer (30a), each in relation to expansion or stretching in the machine direction (MD) and transverse to the machine direction (CD). The invention further relates to a tube produced from such a laminate and the use of such a laminate.
