The present invention is directed to tack-free gels and to methods for manufacturing a tack-free gel pad, in which a discontinuous layer of fluorinated ultrahigh molecular weight polyethylene is permanently bonded to the gel pad to provide a tack-free coating. The gel pad may be incorporated into a gel cap to provide a surgical access device having a tack-free surface.
