摘要

MULTI-LAYER STRUCTURE UNDERSTANDING AT LEAST ONE STABILIZED LAYER The invention is a multi-layer structure comprising at least two layers: - an inner layer, intended to be in contact with a liquid, comprising a composition comprising at least one polymer and not comprising copper, and a so-called outer layer for contact with air, comprising a composition containing at least one polymer and at least one copper-based stabilizer. The invention is also a tube comprising such a multilayer structure as well as its use for transporting or storing fluids.
