Apparatus and process for making a water soluble pouch

An apparatus for making water soluble unit dose pouches comprising:

• a thermoforming mold having a forming surface;
• a plurality of spaced apart recesses in said forming surface, wherein each recess of the plurality of spaced apart recesses comprises a vacuum orifice and each vacuum orifice is in fluid communication with a vacuum source;
• a continuous land area surrounding said plurality of spaced apart recesses, wherein portions of said land area between said plurality of spaced apart recesses have an average roughness Ra from 2.2 μm to 10 μm,
• wherein said forming surface has a forming surface area and said continuous land area has a continuous land area surface area,
• wherein said continuous land area surface area is from 20% to 35% of said forming surface area;
• wherein the water soluble unit dose pouches comprise:
• a first water soluble film;
• wherein said first water soluble film comprises:
• from 50% to 80% by weight of said first water soluble film of polyvinylalcohol polymer;
• from 20% to 50% by weight of said first water soluble film of nonaqueous plasticizer;
• from 1% to 15% by weight of said first water soluble film of 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;
• wherein heat is applied to said first water soluble film upstream of the location at which thermoforming occurs.
