  • Patent number: 10486845
    Abstract: In an embodiment of the present disclosure, a process for producing a flexible pouch is provided. The process includes placing a capillary precursor element (CPE) between two opposing flexible films. The flexible films define a common peripheral edge. The CPE comprises an array of pins sandwiched between two opposing polymeric strips. The process includes positioning a first side of the CPE at a first side of the common peripheral edge and positioning a second side of the CPE at a second side of the common peripheral edge. The process includes first sealing, at a first seal condition, (i) the opposing polymeric strips to each other to form a matrix, and (ii) sealing the matrix to the two opposing flexible films. The process includes removing the array of pins from the matrix to form an in situ microcapillary strip.
