Flexible tube, resistant to stress cracking and impermeable to water vapour

摘要

The invention concerns a tube comprising a wall made of C₄-C₁₀ linear ethylene-olefin copolymer or a mixture of C₄-C₁₀ linear ethylene-olefin copolymer having a melt index ranging between 3 and 10 g/mn, and a density ranging between 0.880 g/cm³ and 0.935 g/cm³ inclusive. The skirt has a mid-height wall thickness ranging between 0.30 and 10 mm inclusive, and a length between 40 and 200 mm inclusive. Furthermore, the skirt and the dispensing head are made in a single injection molding operation in an injection mold. The invention is useful for making tube-like packages.
