First aid
Cohesive bandage and ordinary tape are not the same thing
Why vets, physios and anyone with fragile skin reach for the roll that sticks only to itself.
The difference is one sentence long: cohesive bandage sticks to itself and to nothing else. No adhesive meets skin, hair or fur at any point. Everything else about how it behaves follows from that.
What that changes in practice
Adhesive tape works by bonding to the surface under it. That is fine on a forearm and unpleasant on a hairy leg, painful on thin or elderly skin, and close to impossible on an animal. Removal takes the top layer of whatever it was bonded to, which is why taping a dog is a job nobody volunteers for twice.
A cohesive wrap holds by overlapping itself. The layers grip each other, the assembly grips the limb by gentle compression rather than by glue, and it comes off by unwinding or a single scissor cut with nothing pulling at all.
| Cohesive wrap | Adhesive tape | |
|---|---|---|
| Sticks to | Only itself | Skin, hair, fur, clothing |
| Removal | Unwinds painlessly | Pulls hair and skin |
| On animals | Standard practice | Rarely usable |
| Compression | Even, adjustable by tension | None to speak of |
| Reusable | No, single use | No |
| Tears by hand | Yes | Usually yes |
Where the compression comes from
Tension is applied by the person wrapping, which is both the strength and the risk. Stretched lightly and overlapped by half a width, the wrap supports a joint without restricting circulation. Stretched hard, it becomes a tourniquet, and on a limb that will swell it becomes one an hour after you walked away.
The rule taught in every first aid course applies here: you should be able to slide a finger under the finished wrap. If a wrapped extremity goes cold, pale or numb, it is too tight and the wrap comes off rather than gets loosened.
Why twelve rolls is the normal quantity
Cohesive wrap is single use. It goes on, it does its job, it comes off in the bin. A clinic changing dressings daily, a stable with a horse in recovery, or a physio strapping ankles through a season all consume rolls at a rate that makes a two-roll pack absurd.
Twelve rolls is roughly a month at daily use. It is not a stockpile; it is a reorder cycle, and it is the reason the packs on this site are counted the way they are.
What it does not do
- It is not a wound dressing. Something sterile goes against the wound first; the wrap holds that in place.
- It is not waterproof, though it tolerates damp better than fabric tape.
- It does not immobilise a joint the way a rigid splint does. Support and immobilisation are different jobs.
- It should not be reused. The self-adhesion degrades once unwound and the compression becomes unpredictable.
The full range of wraps sits in the first aid section, with the roll count on every card.
