  • providing a liner material, a release medium, and a capture medium, wherein the capture medium comprises a micorporous hydrophilic polymeric material disposed on a polymer film;

    aligning the release medium with the capture medium in side-by-side, single edge only, overlapping relation to form a single release/capture media layer such that a sequential liquid flow path is formed therethrough;

    aligning the liner material in vertical, parallel alignment with the release/capture media layer; and

    bonding the liner material to a side of the release/capture media layer including the polymer film to form a laminate.
