Duck HD Clear Heavy Duty Packing Tape Refill, 6 Rolls, 1.88 Inch x 54.6 Yard, (441962)

I read the bad reviews and had to add my 2 cents. I have used this tape for years and had the company I work for buy it exclusively for shipping. It's a middle thickness tape - 3M being the thick type that sticks well but is too stiff to hold corners and folds well and the cheap thin type that rips and wrinkles easily like the post office uses. This is the best compromise that dispenses well, is easy to run a straight seem without wrinkles, adheres well, and is strong. I occasionally get some "chips" from it when cut with the saw-tooth blades on most dispensers, but the only way to minimize that is to go too thick. For our application, it's been the best we've found for sealing boxes for shipping.
