The Strongest tape Uline sells. Great for oversize shipments and packages over 60 lbs. 3.5 Mil thick which means it has the strength to make sure your boxes won't break open or come apart. Strong bonding to packages so you don't need to worry about the tape coming off. Clear so you can tape over shipping labels and they can still be seen. Save money by buying 6 rolls at once vs the cost of a single roll.
