Packing tape and a tape gun ranked for UK home sellers sealing boxes and mailing bags, with typical prices and how much each roll seals.
About this ranking
Brown packing tape in 48 mm rolls seals most boxes a home seller posts, and a 6-roll pack costs about £5 to £9. Add a tape gun once you seal more than a handful of boxes a day.
Mailing bags seal themselves, so a Vinted seller posting only bags can skip tape until the first box sale.
How we chose
The criteria that set the order. Commission plays no part.
Run one strip along the centre seam and down each end, an H shape, on the top and the bottom. A single strip lets the corners split open in a sorting machine.
Tape over a reused box's old labels and barcodes so the courier scans only yours.
A tape gun cuts the strip with one movement, so you seal a box in seconds with one hand on the flaps. At ten boxes a day it saves real time and fewer strips stick to themselves.
At one or two boxes a week, tearing by hand is fine.
Mailing bags have a peel-and-seal strip, so tape them only if the strip has lost its grip. A strip of tape over the seal also shows a buyer the parcel arrived unopened.
Reused boxes need their old tape cut away or covered, plus fresh tape on every seam you open. Old tape dries out and lets go.
