Hydrofilm Transparent Film Dressings

Hydrofilm by Hartmann is a thin, transparent adhesive film dressing that seals a wound under a waterproof, breathable barrier. The polyurethane film keeps out water, bacteria, and contaminants while letting oxygen and moisture vapor pass through — so the wound stays protected without becoming trapped and macerated. Because the film is clear, you can inspect the site without disturbing the dressing, which makes Hydrofilm a practical choice for IV sites, post-surgical incisions, superficial wounds, abrasions, and as a secondary cover over other dressings.

The most common question buyers ask is which size to order. Honest Medical stocks the range so you can match the dressing to the wound plus a margin of intact skin around it. The smaller 2.4 x 2.75 inch Hydrofilm (SKU 685755/685756) suits catheter and IV insertion sites and small wounds, while the 4 x 5 inch, 4 x 6 inch, and the Hartmann Hydrofilm 4 x 6 inch dressing (970004) cover larger incisions and areas needing broader protection. Every option here is sterile and individually packaged.

Hydrofilm's 4-tab delivery system is what makes it easy to apply cleanly. The tabs let you position the dressing precisely and peel away the backing without the film folding back on itself — a real advantage when applying single-handed or over an awkwardly placed wound. The frameless, low-profile construction conforms to knees, elbows, and other mobile areas and stays put through showering and daily activity.

Is Hydrofilm waterproof? Yes — the film provides a shower-proof, bacterial barrier while remaining permeable to vapor, which supports moist wound healing. Wear time depends on the wound and exudate level, but transparent film dressings are typically left in place for several days between changes. For heavily draining wounds, pair it with an absorbent primary dressing and use Hydrofilm as the secure outer layer.

Order the sizes your protocol calls for, or mix formats to keep both IV-site and general wound-care needs covered in one place.
