ABSTRACT:
The invention concerns a packaging tube comprising a multi-layer pure plastic laminate and a sealing arrangement for tube heads for the packaging of materials with volatile substances such as flavouring or scent substances, which has a resistance to diffusion which is the same as or comparable to tubes which in their laminate structure have a metal layer as a diffusion barrier and which improves the recycling of tubes.
