A process for making water soluble unit dose pouches comprising the steps of: providing an apparatus comprising: a thermoforming mold having a forming surface; a plurality of spaced apart recesses in said forming surface, wherein each said recess comprises a vacuum orifice and each vacuum orifice is in fluid communication with a vacuum source; a continuous land area surrounding said recesses, wherein portions of said land area between said recesses have an average roughness Ra from 2.2 μm to 10 μm; positioning a first water soluble film in facing relationship with said land area, wherein said first water soluble film comprises: from 50% to 95% by weight of said first water soluble film polyvinylalcohol polymer; from 5% to 50% by weight of said first water soluble film nonaqueous plasticizer; from 1% to 15% by weight of said first water soluble film water; and surfactant; wherein said first water soluble film has a thickness from 20 μm to 150 μm before said first water soluble film is positioned in facing relationship with said land area of said thermoforming mold; heating said first water soluble film; applying vacuum to said first water soluble film through said vacuum orifices to thermoform said first water soluble film to said recesses thereby forming a plurality of open pockets; placing a substrate treatment composition in said plurality of open pockets; positioning a second water soluble film above said first water soluble film; joining said second water soluble film and said first water soluble film thereby forming a web comprising a plurality of closed pouches; cutting said web to separate said closed pouches from one another; and separating said closed pouches from said forming surface. providing an apparatus comprising: a thermoforming mold having a forming surface; a plurality of spaced apart recesses in said forming surface, wherein each said recess comprises a vacuum orifice and each vacuum orifice is in fluid communication with a vacuum source; a continuous land area surrounding said recesses, wherein portions of said land area between said recesses have an average roughness Ra from 2.2 μm to 10 μm; a thermoforming mold having a forming surface; a plurality of spaced apart recesses in said forming surface, wherein each said recess comprises a vacuum orifice and each vacuum orifice is in fluid communication with a vacuum source; a continuous land area surrounding said recesses, wherein portions of said land area between said recesses have an average roughness Ra from 2.2 μm to 10 μm; positioning a first water soluble film in facing relationship with said land area, wherein said first water soluble film comprises: from 50% to 95% by weight of said first water soluble film polyvinylalcohol polymer; from 5% to 50% by weight of said first water soluble film nonaqueous plasticizer; from 1% to 15% by weight of said first water soluble film water; and surfactant; from 50% to 95% by weight of said first water soluble film polyvinylalcohol polymer; from 5% to 50% by weight of said first water soluble film nonaqueous plasticizer; from 1% to 15% by weight of said first water soluble film water; and surfactant; wherein said first water soluble film has a thickness from 20 μm to 150 μm before said first water soluble film is positioned in facing relationship with said land area of said thermoforming mold; heating said first water soluble film; applying vacuum to said first water soluble film through said vacuum orifices to thermoform said first water soluble film to said recesses thereby forming a plurality of open pockets; placing a substrate treatment composition in said plurality of open pockets; positioning a second water soluble film above said first water soluble film; joining said second water soluble film and said first water soluble film thereby forming a web comprising a plurality of closed pouches; cutting said web to separate said closed pouches from one another; and separating said closed pouches from said forming surface.
