Abstract

A process for preparing a water-soluble container which comprises: a) thermoforming a first poly(vinyl alcohol) film having a water content of less than 5 wt % to produce a pocket; b) filling the pocket with a composition; c) placing a second film on top of the filled pocket; and d) scaling the first film and second film together.

Claims

exact text as granted — not AI-modified
1 - 17 . (canceled)  
   
   
       18 . A method of preparing a composition comprising packaging the composition with a thermoformed polyvinyl alcohol film comprising less than 2 wt % water.  
   
   
       19 . A method according to  claim 18  wherein the polyvinyl alcohol film has a thickness before thermoforming of 20 μm to 500 μm.  
   
   
       20 . A method according to  claim 18  wherein the composition is an aqueous liquid.  
   
   
       21 . A method according to  claim 20  wherein the aqueous liquid comprises at least 8 wt % water based on the total weight of aqueous liquid.  
   
   
       22 . A method according to  claim 18  wherein the composition is selected from the group consisting of fabric care compositions, surface care compositions, dishwashing compositions, water-softening compositions, laundry compositions, detergent compositions, disinfectant compositions, antibacterial compositions, antiseptic compositions, agricultural compositions and rinse aid.  
   
   
       23 . The method according to  claim 23  wherein the packaging results in a package comprising the composition and the package is suitable for use in a domestic washing machine.  
   
   
       24 . A method according to  claim 18  wherein the composition is a refill composition for a trigger-type spray.  
   
   
       25 . A method of preparing a composition comprising packaging the composition with a polyvinyl alcohol film comprising less than 2 wt % water and comprising 5 to 35 wt % plasticiser based on the total weight of the film.  
   
   
       32 . A method according to  claim 25  wherein the polyvinyl alcohol film has a thickness before thermoforming of 20 μm to 500 μm.  
   
   
       27 . A method according to  claim 25  wherein the composition is an aqueous liquid.  
   
   
       29 . A method according to  claim 25  wherein the aqueous liquid comprises at least 8 wt % water based on the total weight of aqueous liquid.  
   
   
       29 . A method according to  claim 25  wherein the composition is selected from the group consisting of fabric care compositions, surface care compositions, dishwashing compositions, water-softening compositions, laundry compositions, detergent compositions, disinfectant compositions, antibacterial compositions, antiseptic compositions, agricultural compositions and rinse aid.  
   
   
       30 . A method according to  claim 25  wherein the packaging results in a package comprising the composition and the package is suitable for use in a domestic washing machine.  
   
   
       31 . A method according to  claim 25  wherein the composition is a refill composition for a trigger-type spray.
