Cohesive Bandage Guide: Self-Adherent Wrap Uses, How to Wrap It, and Cohesive vs ACE-Type Wraps

Updated October 2026

The short answer

A cohesive bandage is a stretchy wrap that sticks to itself but not to skin, hair or the dressing underneath. It is also called self-adherent wrap, and often by brand names such as Coban (for people) or Vetrap (for animals). You wrap it, press the end down, and it stays put with no tape, clips or pins.

Use it to hold gauze or a dressing in place, steady an IV or a splint, or add light compression to a sprain. Choose an ACE-type elastic bandage with a hook-and-loop or clip closure instead when you want a wrap you can take off, adjust and reuse through the day.

Whichever you use, the rule is the same: snug, not tight. Leave fingers or toes uncovered so you can check that circulation is normal.

What is a cohesive bandage?

A cohesive bandage is a lightweight, stretchy, porous wrap with a coating that bonds to itself. As Wikipedia puts it, it sticks to its own layers but does not adhere well to other surfaces. That gives it three useful traits:

• No adhesive on the skin. It doesn't grip skin or hair, so removal is gentle, even on fragile skin.
• Nothing to fasten. Wrap, press the end down, and it holds. No clips to lose and no tape to peel.
• It tears by hand. Most cohesive wraps rip cleanly to the length you need, so you don't need scissors.

What is it called? "Cohesive bandage," "self-adherent wrap," "self-adhesive bandage wrap" and "bandage that sticks to itself" all describe the same kind of product. Coban is 3M's brand name for it, and Vetrap is 3M's version for animals. Unity carries cohesive wraps from Medline, CURAD and CoFlex.

Does it contain latex? It depends on the product. 3M says its Coban wrap is made with natural rubber latex, and many other brands offer latex-free versions. If you or the person you care for has a latex allergy, check the label or the product listing before you buy.

What is cohesive wrap used for?

• Holding a dressing in place. Wrap it over gauze or a non-stick pad on an arm, leg, finger or toe, where tape won't stay put. It is a common secondary dressing in clinics and home care.
• After a blood draw or IV. It holds a cotton ball or gauze over the site, or steadies an IV line, without tape on the skin. 3M lists blood draws, dressings and immobilization among Coban's uses.
• Awkward spots. Fingers, toes, heads and ears are hard to dress with a pre-cut bandage. A narrow cohesive wrap shapes around them.
• Light compression and support. Snugly wrapped, it adds light compression for a minor sprain or strain and gently limits movement. Hand therapists also use it to control finger swelling, applied to a set tension.
• Holding a splint or cold pack. It keeps a finger splint or ice pack in place. The Medline Deluxe Instant Cold Pack comes with its own self-adhering wrap.
• Sports. Athletes use it as a quick wrap that holds through sweat; CURAD IRONMAN Self-Adherent Wrap is made for training.
• Kids. Bright colors and patterns can make a dressing less scary, such as CoFlex NL smiley-face wrap and the Medline Kids Pack.

What it is not for: don't put it directly on an open wound. Clean and cover the wound first; our guide to wound cleanser vs saline walks through that. Don't use it in place of a prescribed compression system for leg ulcers or lymphedema; see compression bandages explained.

Cohesive wrap vs ACE-type elastic bandage vs tape

People often ask whether a Coban-style wrap can replace an ACE bandage. For first aid, the two overlap; the difference is how they fasten and how easily you can adjust them.

	Cohesive (self-adherent) wrap	Elastic bandage (ACE-type)	Medical tape
How it holds	Sticks to its own layers	Hook-and-loop ends or clips	Adhesive on skin
On skin and hair	Doesn't stick; gentle removal	Doesn't stick	Sticks; can pull on removal
Adjusting during the day	Unwrap and rewrap	Unwrap and rewrap; ACE guidance advises adjusting it through the day	Replaced
Cut to length	Most tear by hand	Fixed roll length	Tears or cuts
Best for	Holding dressings, IVs, fingers and toes; light compression	Sprains and strains; holding a cold pack or splint	Securing a pad's edges; small dressings
Unity examples	Medline blue cohesive, CURAD Premium cohesive, CoFlex NL	Medline Matrix, CURAD hook-and-loop elastic, CURAD Figure-8 Ankle Wrap	See how to choose medical tape

For an ankle sprain, many people prefer something they can adjust themselves. The CURAD Figure-8 Elastic Ankle Wrap is pre-shaped in a figure-8 pattern and closes with hook-and-loop, so no wrapping skill is needed. Its listing says it gives light support for mild sprains, weak ankles, swelling or tendonitis and fits ankles from 7.5 to 11 inches. A wrap is not a brace: MyHealth Alberta notes that compression alone doesn't protect the joint when you put weight on it.

How to apply a cohesive wrap, step by step

These steps draw on NHS patient leaflets from University Hospital Southampton and Royal Devon. If a nurse or therapist showed you a specific method or tension, follow theirs.

1. Cover any wound first. Cohesive wrap goes over a dressing, never directly on an open wound.
2. Pick the width. Narrow rolls (1 inch) suit fingers and toes; wider rolls suit wrists, ankles and limbs.
3. Unroll a little first. Pull a few inches off the roll and let it relax before you start, so you don't wrap with hidden tension.
4. Start farthest from the heart. Begin at the fingertip, toes or below the dressing and work upward. Leave the tip of the finger or toes showing so you can check circulation.
5. Anchor the first turn without stretching. Press the overlap lightly so it grabs.
6. Overlap each turn by half. Keep the wrap smooth, with no wrinkles or twists, so pressure stays even.
7. Use only the tension you need. To hold a dressing, lay the wrap on with almost no stretch. For light compression on a sprain, keep it taut but not tight. Don't pull a roll to full stretch as you wrap.
8. Finish without stretch. Tear or cut the end, ease off the tension on the last turn and press it down.
9. Check circulation right away and often. Press the fingertip or toenail: it should turn white, then go back to normal color straight away. Unwrap and rewrap more loosely if the skin beyond the wrap turns white, blue or purple, feels cold, numb or tingly, or swells.
10. Give the skin a break. Unless a clinician tells you otherwise, don't sleep in a compression wrap, and check the skin under it for redness or irritation.

How to choose a cohesive wrap

• Width. Most cohesive rolls come 5 yards long in widths from 1 to 6 inches. Keep a narrow roll for fingers and toes and a wider one for limbs.
• Latex. If anyone in your care has a latex allergy, choose a roll whose listing says it is made without natural rubber latex, such as CoFlex NL or the Medline blue cohesive bandage.
• Color. Tan blends in; bright colors and patterns are easy to spot and popular with kids. Black suits sports, as with CURAD IRONMAN.
• Single roll or case. For a home first aid kit, a single roll or two is enough. CURAD Premium cohesive sells by the roll or by the case. Clinics, schools, athletic programs and home-health agencies usually buy cases: 18 rolls of 4-inch up to 36 rolls of 2-inch on most Unity listings. Orders over $50 ship free.
• Cohesive or elastic? If the main job is holding a dressing or an IV, choose cohesive. If it is supporting a sprained ankle or wrist that you will rewrap through the day, an elastic wrap with self-closure or the figure-8 ankle wrap is easier to adjust.

Stocking a kit? Alongside cohesive wrap, every first aid kit should have a CPR breathing barrier. See our guide to CPR face shields vs pocket masks.

Frequently asked questions

What is another name for Coban wrap?

Coban is 3M's brand name. The generic names are cohesive bandage, self-adherent wrap and self-adhesive bandage wrap. Vet wrap (Vetrap is 3M's brand) is the same type of product sold for animals.

Can you use vet wrap on people?

Vet wrap and human cohesive bandage work the same way: both stick only to themselves. For people, choose a wrap sold for human first aid, so you can check its latex status and labeling.

Can I use a cohesive wrap instead of an ACE bandage?

For many first-aid jobs, yes: both can add light compression and hold a cold pack or splint. An ACE-type elastic bandage is easier to take off and rewrap during the day. A cohesive wrap is better at holding dressings and fitting fingers, toes and small joints.

How long can a cohesive wrap stay on?

Follow your clinician's instructions. Hand therapy leaflets from the NHS advise against wearing it day and night without a break, and one says not to wear it while asleep. Replace it if it gets wet or dirty, and check the skin underneath each time.

When should you not use a cohesive wrap?

Don't put it directly on an open wound. Don't use a latex-containing wrap on anyone with a latex allergy. Take it off and get medical advice if pain, numbness, tingling or color changes don't settle once you loosen it.
