Why Thickness and Price are not Indicators of Tape Quality

When many manufacturers go to market in search of tape to use for case sealing applications, the primary concern often seems to be the tape’s thickness (in mils) and the price. Purchasers often think to themselves, “Okay, which tape has the best mil rating/price ratio?”. However, this can cause many problems.

Let us take a look at a comparison between Shurtape’s AP 180 emulsion acrylic carton sealing tape vs. a competitor’s version.

Shurtape Competitor
Mil 1.9 1.9
Tensile (lbs./in. width) 27 30
Adhesion to Steel (oz/in. width) 44 4
Elongation % at breaking point 150 130
Holding Time (in hours) 15,000 6,000
Figure 1

Figure 1 indicates that the Shurtape brand shares the same mil rating as the competitive tape, and even has a lower tensile strength. However, 27 lbs./inch width is still relatively strong! Additionally, Shurtape’s version maintains 11x the adhesion to steel than the competition, a longer elongation-to-break, and a much longer holding time! This longer holding time and better elongation rate both translate to more economical tape usage and a much longer-lasting seal on your packages. If you are in need of a strong seal that will last long enough for your needs, Shurtape is the way to go.

Of course, it always comes down to the application and its needs. No tape is the single best tape. However, in search of your next tape source, it is very important not to default to the very common, yet flawed analysis of mil thickness/price.
