In an embodiment of the present disclosure, a method for creating a flexible pouch is provided. The method includes positioning a capillary precursor element (CPE) between two opposing flexible films. The flexible films define a common peripheral edge. The CPE comprises an array of fingers sandwiched between two opposing polymeric strips. The method includes placing a first side of the CPE on a first side of a common peripheral edge and a second side of the CPE on a second side of a common peripheral edge. The method includes, in a first sealed state, (i) first sealing opposing polymeric strips to each other to form a matrix, and (ii) sealing the matrix to two opposing flexible films. The method includes removing an array of fins from the matrix to form fine capillary strips in situ . |
