I like to use Scotch Storage Tape as it is a very strong tape and has always given me good results. It is clear and is particularly good for sealing boxes.
I'm sure there are many other uses for this tape as well, but the use I find it the best for is sealing those packages I intend to send through the mail or through UPS. I don't want my boxes coming apart en route, and this tape has proven to be excellent for sealing up the box and holding on labels so that I am confident that the package will reach its destination without any problems. My husband uses it as well, and claims that he is very happy with the performance of this tape.
We have a professional-type dispenser that the roll of tape is put on, and it makes quick and easy work of sealing up a package and getting it ready for shipment. And since the tape is clear, we use it to attach labels to the package without having to worry about any of the writing on the label being obscured. We cover the entire label with tape and it keeps the label not only firmly affixed to the package, but also protects the ink from running should the package get wet.
Both my husband and I like using Scotch Storage Tape.
