Packaging with improved water vapour barrier rating

Abstract

Packaging means made of plastic, in particular, for a free-flowing or pourable surfactant-containing and/or bleach-containing material, for example detergent or cleaning agent powder, comprising a base, a top and a body, wherein the packaging means has a water vapor permeability level>15 g/(m 2 *d) and wherein at least the body of the packaging means is covered over, in part, by a sheet-like presentation and identification means which butts against the outer surface of the packaging means and has a water vapor permeability level<15 g/(m 2 *d).

1 . Packaging for free-flowing or pourable surfactant-containing and/or bleach-containing packaged goods agent comprising:
 a base,   a top, wherein an opening for removing product from the packaging is located on or in the top and the opening can be closed with a closing means, and   a body,   wherein the packaging is made of plastic and has a water vapor permeability>15 g/(m 2 *d),   wherein at least the body of the packaging is covered, at least in part on the external surface of the packaging, by a film-like presentation and identification means having a water vapor permeability<15 g/(m 2 *d), the presentation and identification means covers 50% to 95% of the packaging surface, and the presentation and identification means is fixed on the packaging by adhesion.   
   
   
       2 . Packaging according to  claim 1  wherein the film-like presentation and identification means completely encloses the body surface and at least leaves part of the base uncovered. 
   
   
       3 . Packaging according to  claim 1  wherein the film-like presentation and identification means at least covers sections of the base and/or the top of the packaging. 
   
   
       4 . Packaging according to  claim 1  wherein the film-like presentation and identification means at least covers sections of the closing means. 
   
   
       5 . Packaging according to  claim 1  wherein the adhesive layer has a water vapor permeability that is lower than that of the packaging. 
   
   
       6 . Packaging according to  claim 1  wherein the adhesive layer has a water vapor permeability that is lower than that of the film-like presentation and identification means. 
   
   
       7 . Packaging according to  claim 1  wherein the adhesive layer is applied onto substantially the whole surface between the film-like presentation and identification means and the packaging. 
   
   
       8 . Packaging according to  claim 1  wherein the film-like presentation and identification means is interlockingly joined to the packaging by means of in-mold labeling. 
   
   
       9 . Packaging according to  claim 1  wherein the thickness of the film-like presentation and identification means is between 5 μm and 100 μm. 
   
   
       10 . Packaging according to  claim 1  wherein the ratio of the wall thickness of the packaging to that of the film-like presentation and identification means is >1. 
   
   
       11 . Packaging according to  claim 1  wherein the film-like presentation and identification means is arranged in at least a single layer around the packaging. 
   
   
       12 . Packaging according to  claim 1  wherein the film-like presentation and identification means is printed. 
   
   
       13 . Packaging according to  claim 1  wherein the film-like presentation and identification means is printed on the surface of the packaging. 
   
   
       14 . Packaging according to  claim 1  wherein the film-like presentation and identification means is detachably arranged on the packaging. 
   
   
       15 . Packaging according to  claim 1  wherein an opening aid is provided on or in the film-like presentation and identification means. 
   
   
       16 . Packaging according to  claim 1  wherein the film-like presentation and identification means is fixed on the packaging by means of a detachable adhesive bond. 
   
   
       17 . Packaging according to  claim 1  wherein the ratio of body surface to the surface of the top and the base is greater than 2. 
   
   
       18 . Packaging according to  claim 1  wherein the packaging is molded from a bioplastic. 
   
   
       19 . Packaging according to  claim 18  wherein the bioplastic is cellulose-based plastic, plastic based on polylactic acid (PLA), polyhydroxybutyrate (PHB), polyhydroxyvalerate (PHV), polyhydroxyalkanoate (PHA), thermoplastic starch blends, polycaprolactone (PLC) or any blends thereof. 
   
   
       20 . Packaging according to  claim 1  wherein the packaging is not printed.
