What is Carton Sealing Tape?

Carton sealing tape (also pressure-sensitive packing tape) varies in terms of usage but is generally used on corrugated boxes.

For example “Super Tape” brand Acrylic Carton Sealing Tape is best suited for reliable, all-temperature box sealing performance (less than 40°F and greater than 120°F) where resistance to aging, weathering, UV light and yellowing are important.

What is Mil Thickness?

Mil thickness is measured using a micrometer and gauges how thick the tape is. Depending on the application, you may need a tape with more adhesive and with a higher thickness.

Hey everyone, Ricky Chu from Chu’s Packaging Supplies. Today, I’m going to talk to you about carton sealing tape and the mil thickness. What is mil thickness and how much of it do you really need? Carton sealing tape is pretty simple. There’s two parts to it. The backing and the side that has adhesive, the more adhesive that’s coated on the thicker the tape and the stronger the adhesive is. To measure thickness, we use a micrometer like this. And so this is a two mil tape. You see our super tape red core means two mils. Micrometer will show you it’s exactly 2 mils. This is our super tape blue core which is at 1.8 mil

Mics out at just at 1.8 mil. Generally light duty jobs require a 1.6 mil. Medium duty is at 1.8. Heavy duty is a 2.0 mil and anything above that is super heavy duty, but nowadays you can find every mil thickness in-between. Some people want to get a 1.7, some people want a 2.1. To choose the right mill thickness, you have to think about two things. One is how heavy, the product weighs that you’re trying to ship. And two, how much you want to spend on it, because the thicker you go, the more adhesive is on there, the more money you’re going to spend on the tape. So if you have a light duty job, you can save some money by going to 1.6, 1.8.

You want to make sure your shipments get there securely a little bit heavier, definitely go 2 mil and above. For more information on our entire product line and our carton sealing tapes, please visit our website at www.chuspkg.com.
