Abstract
A web (8) of cleaning products (10) and a method of manufacturing the same is disclosed. The web includes first (20) and second carrier (30) sheets and a plurality of pouches (50) containing a cleaning composition. Each of the pouches is disposed in a respective depression (26) formed in an upper surface (28) of the first carrier sheet. A first internal atmosphere (80) is enclosed within each of the pouches. The first carrier sheet is sealed to the second carrier sheet such that a second internal atmosphere (82) exists between the second carrier sheet and the plurality of pouches. The second internal atmosphere has a greater absolute pressure (P) than the first internal atmosphere so that the plurality of pouches and at least a portion of the cleaning composition in the plurality of pouches are compressed into the plurality of depressions in the first carrier sheet by the second internal atmosphere.
