Abstract

A flexible tube skirt (10) has a primary film (20) and a decorative film (30), wherein the decorative film (30) has a decoration substrate and a sealable outer layer (33) The decoration substrate is applied on all of at least one of the surfaces of the primary film (20) and is below the sealable outer layer (33). The flexible tube skirt may be used in a flexible tube.

First claim

The invention claimed is:

1. A flexible tube skirt comprising a primary film and a decorative film,
wherein said decorative film comprises a decoration substrate having a first surface and a second surface opposite the first surface and a sealable outer layer applied to the first surface of the decoration substrate,
said primary film having a first surface and a second surface opposite the first surface, said second surface of the primary film comprising an outer sealable layer,
said second surface of the decoration substrate being applied on all of the first surface of said primary film,
the flexible tube skirt comprising an overlap side seam, wherein said sealable outer layer of the decorative film is sealed with the outer sealable layer of the primary film, the decoration substrate being present in the overlap side seam,
said primary film being a multilayer film comprising at least one ethylene vinyl alcohol (EVOH) barrier layer.

2. A flexible tube skirt according to claim 1 , wherein said decoration substrate comprises a base layer and a decoration, said decoration being applied on said base layer.

3. A flexible tube skirt according to claim 2 , wherein said decoration is applied to form a metallized, holographic and/or printed surface on the base layer.

4. A flexible tube skirt according to claim 2 , wherein said base layer is selected from polypropylene, polyethylene and/or polyethylene terephthalate.

5. A flexible tube skirt according to claim 2 , wherein said decoration is applied to be visible through said sealable outer layer of the decorative film and/or visible through said primary film.

6. A flexible tube skirt according to claim 2 , wherein said decorative film further comprises printing on the decoration and/or on the sealable outer layer.

7. A flexible tube skirt according to claim 1 , wherein said sealable outer layer of said decorative film is transparent and comprises PE material.

8. A flexible tube skirt according to claim 1 , wherein said primary film is a blown film.

9. A flexible tube skirt according to claim 8 , wherein said primary film is a multi-layer film representing at least 70% by mass of the final flexible tube skirt.

10. A flexible tube skirt according to claim 1 , wherein said primary film is printed on its first surface.

11. A flexible tube comprising a flexible tube skirt according to claim 1 .
