Mefix is a self-adhesive fabric for secure fixation. The porous structure of the Sontara nonwoven fabric ensures air and water vapour permeability. Mefix is a flexible dressing that conforms well to the body contours and allows body movement when in place. Mefix is non-absorbent and hydrophobic flexible dressing that reduces the potential of blood and fluid strike-through by increasing overall absorbency of the dressing. Mefix has a polyacrylate adhesive which is designed to be gentle to the skin and provide secure fixation.

Mefix is ranked as the best flexible dressing on the market allowing for easy shaping to the body. Mefix medical tape because of its flexibility allows blood to flow while allowing for full body movement when the dressing is in place.
