Sticker Mule’s custom packaging tape uses a water‑activated adhesive, not a typical “peel-and-stick” pressure-sensitive glue.

How the adhesive is activated

  • The tape arrives dry and not sticky to the touch.
  • The adhesive is on the unprinted (back) side of the tape and is activated only when you apply water.
  • Once moistened, the adhesive penetrates the surface fibers of corrugated cardboard and forms a strong, permanent bond as it dries.

A simple example: you cut a strip of tape, swipe the back with a damp sponge, then apply it firmly to a cardboard box; as the water soaks in and evaporates, the tape “locks” into the box surface.

How to use Sticker Mule packaging tape

  1. Cut the length of tape you need.
  1. Wet the non-printed side using a wet sponge (Sticker Mule includes one with your order) or a water-activated tape dispenser.
  1. Apply the tape to the box, starting at one edge and smoothing across to avoid bubbles.
  1. Press firmly so the moist adhesive fully contacts and soaks into the cardboard fibers.
  1. Let it dry undisturbed; the bond becomes very strong as it sets.

When it works best (and when it doesn’t)

  • Works best on:
    • Corrugated cardboard shipping boxes.
* Clean, dry, dust-free surfaces.
  • May not bond well to:
    • Boxes with plastic film coatings.
* Heavily painted or glossy surfaces where water cannot penetrate.

If your boxes are coated or very glossy, you may need to test a strip or switch to a different closure method on those specific surfaces.
