About branded tape offered by Packway:
48mm tape, but other widths are available.
48mm tape is packed 36 rolls per box.
Minimum order quantity is 5 boxes.
This means 180 rolls minimum order if the width is 48mm.
Minimum length per roll is 50m. 
Minimum order is still 5 boxes if the length per roll is 100m.

If you need white, whether as background or letters or part of a logo, the white tape is slightly cheaper than a coloured tape.
For the lettering or other areas to be white, the colours can be printed onto a white tape, leaving the white standing out, but there will be white
lines across the tape between the one print and the next.

We at Packway can provide you with an example.
Packway offers to print colours.
Colour is not guaranteed by Packway.
This applies to the base tape shade or tone and to the shade or tone of the printed colours.

Once-off costs apply to the first print.
