Method for producing a water soluble package

Abstract

A process for the preparation of a package containing a compacted particulate composition, comprising: a. placing a compacted particulate composition on a first film; b. positioning a second film over said composition; and c. sealing said first film to said second film and at least partly evacuating the atmosphere from the inside of said package so as to allow said first film and said second film to cling to said composition.

1 . A process for the preparation of a water-soluble package containing a compacted particulate composition, comprising: 
 a. placing a compacted particulate composition on a planar first water-soluble film;    b. positioning a second water-soluble film over said composition; and    c. sealing said first water-soluble film to said second water-soluble film and at least partly evacuating the atmosphere from the inside of said package so as to allow said first water-soluble film and said second water-soluble film to cling to said composition.    
   
   
       2 . A process according to  claim 1  wherein the atmosphere is at least partly evacuated from the inside of said package via a conduit and removing said conduit while or after said films are sealed together.  
   
   
       3 . A process according to  claim 1  wherein the atmosphere is at least partly evacuated from the inside of said package by applying suction to at least one hole in said first film and/or said second film.  
   
   
       4 . A process according to  claim 1  wherein the atmosphere is at least partly evacuated from the inside of said package by sealing said first film to said second film under a vacuum.  
   
   
       5 . A process according to  claim 1  wherein the package is made by a skin-wrapping process or a drape forming process.  
   
   
       6 . A process according to  claim 1  wherein said first film and said second film are sealed together by heat sealing.  
   
   
       7 . A process according to  claim 1  wherein said first polymer is a poly(vinyl alcohol).  
   
   
       8 . A process according to  claim 1  wherein said second polymer is a poly(vinyl alcohol).  
   
   
       9 . A process according to  claim 1  wherein the compacted particulate composition has a surface roughness R a  of from 10 to 20 μm.  
   
   
       10 . A process according to  claim 1  wherein the particulate composition is a fabric care, surface care or dishwashing composition.  
   
   
       11 . A process according to  claim 10  wherein the composition is a dishwashing, water-softening, laundry, detergent or rinse aid composition.  
   
   
       12 . A process according to  claim 1  wherein the composition is a disinfectant, antibacterial or antiseptic composition.  
   
   
       13 . A process according to  claim 1  wherein the composition is an agricultural composition.
