Packaging with improved water vapour permeability

Abstract

Packaging means made of plastic, in particular for a free-flowing or pourable surfactant-containing and/or bleach-containing material, for example, a detergent or cleaning powder, comprising a base, top and 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 enclosed, 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 comprising:
 a floor,   a top, wherein an opening for removing product from the packaging is located on, in or near the top and the opening can be closed with a closing means, and   a lateral surface,   wherein the packaging is made of plastic and has a water vapor permeability >15 g/(m 2 *d),   wherein at least the lateral surface of the packaging is enclosed at least in sections 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) and a modulus of elasticity of at least 200 N/mm 2 , and   wherein the film-like presentation and identification means is a shrink film or a stretch film.   
   
   
       2 . Packaging according to  claim 1  wherein the presentation and identification means completely encloses the packaging. 
   
   
       3 . Packaging according to  claim 1  wherein the presentation and identification means covers between 50% and 95% of the packaging surface. 
   
   
       4 . Packaging according to  claim 1  wherein the presentation and identification means covers between 50% and 100% of the lateral surface. 
   
   
       5 . Packaging according to  claim 1  wherein the presentation and identification means encloses the lateral surface and leaves at least sections of the bottom uncovered. 
   
   
       6 . Packaging according to  claim 1  wherein the presentation and identification means at least covers sections of the bottom and/or the top of the packaging. 
   
   
       7 . Packaging according to  claim 1  wherein the presentation and identification means at least covers sections of the closing means. 
   
   
       8 . Packaging according to  claim 1  wherein the presentation and identification means is friction locked to the packaging. 
   
   
       9 . Packaging according to  claim 1  wherein the presentation and identification means is fixed to the packaging by shrinking or stretching. 
   
   
       10 . Packaging according to  claim 1  wherein the presentation and identification means is cohesively fixed to the packaging. 
   
   
       11 . Packaging according to  claim 10  wherein the cohesive fixture is at least an adhesive layer having a water vapor permeability lower than that of the packaging. 
   
   
       12 . Packaging according to  claim 11  wherein the adhesive layer has a water vapor permeability that is lower than the presentation and identification means. 
   
   
       13 . Packaging according to  claim 11  wherein the adhesive layer is applied onto the surface between the presentation and identification means and the packaging. 
   
   
       14 . Packaging according to  claim 1  wherein the thickness of the presentation and identification means is between 5 μm and 100 μm. 
   
   
       15 . Packaging according to  claim 1  wherein the ratio of the wall thickness of the packaging to that of the presentation and identification means is >1. 
   
   
       16 . Packaging according to  claim 1  wherein the presentation and identification means is arranged in at least a single layer around the packaging. 
   
   
       17 . Packaging according to  claim 1  wherein the presentation and identification means is printed. 
   
   
       18 . Packaging according to  claim 17  wherein the presentation and identification means is printed over its whole surface. 
   
   
       19 . Packaging according to  claim 1  wherein the presentation and identification means is detachably arranged on the packaging. 
   
   
       20 . Packaging according to  claim 1  wherein an opening aid is provided on or in the presentation and identification means. 
   
   
       21 . Packaging according to  claim 1  wherein the presentation and identification means is fixed on the packaging by a detachable adhesive bond. 
   
   
       22 . Packaging according to  claim 1  wherein the ratio of lateral surface area to top and bottom surface area is greater than 2. 
   
   
       23 . Packaging according to  claim 1  further comprising an opening aid for opening the packaging, wherein the opening aid is provided on the packaging. 
   
   
       24 . Packaging according to  claim 23  wherein the opening aid is designed as a perforation. 
   
   
       25 . Packaging according to  claim 23  wherein the film-like presentation and identification means covers the opening aid on the packaging. 
   
   
       26 . Packaging according to  claim 23  wherein the opening aid of the presentation and identification means is arranged not to overlap with the opening of the packaging. 
   
   
       27 . Packaging according to  claim 1  wherein the packaging is molded at least in part from bioplastic. 
   
   
       28 . Packaging according to  claim 27  wherein the bioplastic is a cellulose-based plastic, a plastic based on polylactic acids (PLA), polyhydroxybutyrate (PHB), polyhydroxyvalerate (PHV), polyhydroxyalkanoate (PHA), thermoplastic starch blends, polycaprolactone (PLC) or any mixtures thereof.
