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.

Carton Sealing Tape – A Review of Specifications May Make All the Difference in Your Carton Closing Application

Packaging%20Tapes%20Square%20When it comes to pressure sensitive packaging tape, there is a sea of options out there and deciding the best option for your application can sometimes be a daunting task. Many of you may succumb to “analysis paralysis” and go with the “vanilla” variety of the bunch – the 2” x 100 or 1,000 yards x 2 mil. This may be a perfect fit for many carton sealing applications, but one size certainly doesn’t fit all. So many variables such as storage, shipping, and handling methods can influence your carton sealing demands and needs. If you are shipping that Susie Talks A lot from your fulfillment center in Kansas City to someone’s niece in Fairbanks, Alaska or packaging that delicious Heinkel’s Smoked Turkey Breast in a carton and storing it in the refrigerator, you want to feel confident that your tape is going to stick and keep your product and carton secure through all of its travels.

Here are a few of the primary tape specifications to consider in your pressure sensitive tape selection process:

Size

  • 2” wide vs. 3” wide – When selecting the proper width of tape a couple of primary factors includes the surface area you will be covering and the weight of the package. The 3” width is a good choice when transitioning from using a more expensive and labor intensive water activated tape.
  • Hand Length (55 or 110 yard rolls) used in manual pack stations vs. Machine Length (1,000 yards or more) for use in automated lines.

Adhesive Type

Your packaging, shipping, and storage environments will help determine the best type of adhesive for your carton sealing application:

  • Hot Melt Carton Sealing Tapes – are made with high performance synthetic rubber/resin adhesives and very versatile in a wide range of packaging applications.
  • Emulsion Acrylic Carton Sealing Tapes – are made with high quality emulsion acrylic adhesives for special packaging applications requiring extreme temperature performance.
  • Solvent Acrylic Carton Sealing Tapes – are ultra-clear and feature a premium solvent-based acrylic adhesive system with excellent initial tack for those dusty packaging environments. They perform very well in extreme temperatures, making it an excellent choice for moisture & solvent resistance as well as resistance to aging, yellowing, and UV degradation.

Thickness

  • The thickness of tape is measured in mils. The total mil thickness is made up of the thickness of the film and the thickness of the adhesive. For example, Shurtape’s HP200 Hot Melt Carton Sealing tape has total mil thickness of 1.9. The film thickness makes up 1.2 mils of the total 1.9 mil thickness.
  • Package weight, handling, and storage environments are key considerations when determining the thickness of tape. In many applications we have seen cases where the customer may be using a higher grade and total mil thickness of tape than what is needed for their particular application, so a thorough review of the packaging application is worth the time in possible money savings in the end.

Custom Print

  • Many pressure sensitive carton sealing tape companies now offer the option of custom printing capabilities. If you would like to boost your brand, you have the option of having your company logo printed on the tape as well as any other custom print such as special handling messages.
