How cohesive wrap works
Solventum (formerly 3M health care) describes Coban self-adherent wrap as a non-sterile elastic compression wrap that works like a tape but sticks only to itself, not to skin, hair, drapes or clothing. It says the wrap does not need adhesives, clips, pins or tape, stays in place with minimal flagging at the ends, and can be cut to length with scissors.
Solventum lists uses including holding dressings in place, securing devices, and supporting strains and sprains, and calls the wrap lightweight and breathable. For a reusable clip-on alternative, see our elastic bandage wrap guide.
Latex vs non-latex
| Feature | Coban (with latex) | Coban NL (non-latex) |
|---|---|---|
| Latex | Contains natural rubber latex | Non-latex |
| Tearing | Cut with scissors | Can be torn by hand |
| Construction | Two layers | Single layer with a hand-tear scrim |
| Sterile options | Non-sterile only | Sterile and non-sterile |
| Example size | 3.94 in x 4.5 m | 2 in x 5 yd |
Solventum says both versions have the same specifications for tensile strength and cohesion and are intended for the same general clinical uses. If you have a latex allergy, choose a product labeled non-latex.
3M says Coban NL is suitable for all patients, including those with fragile and at-risk skin, and is made of a nonwoven, elastic material. Its listed uses include blood draws, dressings and immobilization.
Common uses at home
- Holding a dressing. Wrap over gauze on an arm, leg, finger or toe without tape touching the skin.
- Hard-to-dress areas. Solventum lists the head, toes and fingers as difficult areas where the wrap helps.
- Sprains and strains. MedlinePlus first aid for a sprain includes wrapping a bandage around the area to limit movement, firmly but not tightly.
- After a blood draw. Solventum lists blood draws among its clinical uses.
Cohesive wrap is also sold as vet wrap for pets. Products marketed for animals may not list the same details, so for people choose a product labeled for human use.
Wrapping without making it too tight
Self-adherent wrap keeps applying pressure, and Solventum notes it maintains mild compression. That makes it easy to wrap too tightly.
- Firm, not tight, as MedlinePlus advises for sprains.
- Loosen right away if fingers or toes go numb, tingle, turn pale or blue, or feel cold.
- Be extra careful on fingers and toes, where a small wrap can restrict blood flow.
- Leave compression therapy to professionals. Solventum says its wrap may be used as part of a compression wrap system only under the supervision of a wound care specialist.
Choosing a width and pack
- Width. Coban NL comes in widths from 1 inch to 6 inches; narrow rolls suit fingers and toes, wider rolls suit limbs.
- Length. Solventum lists a Coban roll at 4.5 m long; Coban NL comes in 5 yd rolls and 1.6 yd single-use rolls.
- Single-use rolls. Solventum says individually packaged single-use rolls can help reduce the risk of cross-contamination.
- Color. Tan blends in; bright colors are easy to spot on a child.
- Intact skin. 3M notes its medical securement products are intended for use on intact skin, so cover open wounds with a dressing first.
Reuse and care
Cohesive wrap is often used once. 3M's ACE care guide notes that washing gradually reduces how well self-adhering bandages stick, so a washed wrap may not hold as well. Replace a wrap that has lost its grip or stretch.
See a doctor for a suspected broken bone, a joint that looks out of position, severe pain, or a wound that becomes red, warm or painful or causes fever, as MedlinePlus advises for sprains.
