Duct tape is a cloth-backed, rubber-adhesive tape that sticks to almost anything, seals gaps, patches tears and can be torn to any length by hand. It has been a staple of emergency kits, tool bags and glove boxes for decades because it solves so many different problems with one roll: taping over a cracked tent pole, sealing a leaking pipe, patching a punctured tarp, splinting a finger, or bundling loose gear together. A single roll typically runs from around 3 to 50 metres depending on the size bought, and UK prices generally sit between £3 and £10 a roll.
Zip ties (cable ties) are plastic strips with a ratcheting head that pull tight and lock, giving a fast, permanent-feeling bind between two points. They are the go-to for securing loose cables, lashing a tarp to a frame, fixing a wobbly gate, bundling firewood, or making an improvised repair where something needs to be held firmly rather than sealed or patched. A pack of 100 mixed-size ties typically costs £5 to £12 in the UK, working out to pennies per repair, and they take up almost no space in a kit.
| Feature | Duct Tape | Cable Ties |
|---|---|---|
| Primary job | Sealing, patching and covering: closes gaps, stops leaks, covers punctures and splints small breaks. | Binding and fastening: pulls two or more points together and holds them under tension. |
| Reusability | Single use per application; once stuck down it is awkward to remove and reposition cleanly. | Single use once ratcheted tight (cutting is the only way off), though releasable ties exist for repeat use. |
| Weatherproofing | Good short-to-medium-term water resistance when applied to a clean, dry surface, but adhesive can fail in prolonged wet or cold. | Unaffected by water; UV exposure over months can make standard nylon ties brittle, so UV-stabilised ties last longer outdoors. |
| Strength under load | Tears along the weave and has limited holding strength under sustained pulling or weight. | Strong tensile hold once ratcheted; a heavy-duty tie can support real load without stretching. |
| Pack size and weight | A roll is bulkier and heavier; wrapping a flattened length round a card or pencil saves space. | A pack of 100 is flat, light and takes up almost no room in a pouch or glove box. |
| Typical emergency uses | Patch a tent or tarp tear, seal a cracked container, wrap a wound dressing, splint a finger, tape over broken glass. | Secure a tarp to a frame, bundle cables or firewood, fix a loose gate or fence panel, make an improvised hanger or handle. |
| Price band | Roughly £3 to £10 per roll depending on length and brand. | Roughly £5 to £12 for a mixed pack of 100, a few pence per repair. |
Reach for duct tape when the problem is a gap, tear or leak that needs covering or sealing rather than binding. It is the better choice for patching a torn tarp or waterproof jacket, sealing a cracked water container, covering a sharp edge, wrapping round a dressing to hold it in place, or making a quick splint. Its ability to be torn by hand into any length, without tools, makes it faster than a zip tie for irregular or curved repairs where you need the material to conform to a surface rather than cinch two points together.
Reach for zip ties when two things need to be pulled together and held firmly, especially under tension or outdoors over time. They outperform tape for securing a tarp to poles, bundling and organising cables or firewood, fixing a loose hinge or gate, or making an improvised carrying handle, because the ratchet mechanism keeps tightening rather than relying on adhesive that can peel in the rain or cold. A pack of assorted sizes covers most jobs from delicate bundling to heavy-duty lashing.
These are not really substitutes; a well-stocked kit carries both because they solve different problems. Duct tape seals, patches and covers, while zip ties bind and fasten under tension. If space is genuinely tight, a flattened length of tape wound round a card plus a handful of assorted zip ties will together weigh next to nothing and cover the vast majority of field repairs, from a torn tarp to a loose tent pole, that either one alone could not fix as well.
A 50-metre roll of 3M's general-purpose cloth duct tape for the repairs and improvised fixes that come up in any emergency. It tears by hand and sticks to most surfaces, so it earns its place taping tarps, sealing gaps or patching kit in the field. A trusted-brand roll is worth keeping in the grab bag and the car.
A heavy-duty cloth tape that sticks hard to rough, uneven and damp surfaces. The go-to for fast, strong field repairs when something absolutely has to hold.
Strong, weather-resistant cable ties for securing, bundling and repairing almost anything — a featherweight, do-everything fastener for kits, cars and toolboxes.
