Polypropylene Packaging Tapes

Where Price Meets Performance

Carton sealing tape is generally recognized as the most cost-effective way to securely close a box. The term “carton sealing tape” is an industry term, but they may be called by many different names – polypropylene packaging tapes, poly tape, box sealing tape, or many others. Although they are one of the more economical types of tapes, it is important that cost does not become the only consideration. If a carton sealing tape fails, the costs can be far greater.

What Type of Carton Sealing Tape is Best?

The most important factor is the adhesive. There are three primary types of adhesive used to make carton sealing tapes – hot melt, acrylic, and natural rubber adhesive. When selecting a carton sealing tape, the first consideration should always be the bonding surface. Today’s boxes are made from a variety of corrugated paper, with different textures and finishes. Another important factor is the environment, such as storage temperatures, humidity, and useful life of the tape. Hot melts and acrylics are by far the most common adhesives used in carton sealing tape today, and their suitability for your specific application should always be a consideration.

How Strong of a Tape Should I Use?

The amount of adhesive on carton sealing tape is measured in mil thickness using a micrometer (1 mil is 1/1,000th of an inch). Mil thickness usually varies from 1.6 mil to 2.0 mil in carton sealing tapes:

MIL Thickness
Light Duty1.6 mil
Medium Duty1.8 mil
Heavy Duty2.0 mil
Super Duty>2.0 mil

While there are specific adhesion tests, the best tape for an application is the tape a customer tests itself and is satisfied with. Generally, you should select the lightest-duty necessary from a cost standpoint, but also choose a tape where one strip is sufficient to close and hold the box. As a box sealing tape supplier, Spectape provides samples for testing and evaluation so you can determine which works best.

what other factors should i consider?

It is important to evaluate color, surface texture, ease of application, and even printing – which may be equally important to make that professional impression for your customers.

Of course, cost is an important consideration, but sometimes the most economical tape isn’t necessarily the best solution, especially if an economical tape winds up requiring double, or even triple layers to secure the package. Finally, sizing can be important. Carton sealing tapes come in 2″ or 3″ widths and are typically 55 yards or 110 yards in length. However, there are never any “one size fits all” solutions.
