Tape Recommendation Guide - Choosing the Best Box Sealing Tape

Choosing the correct packaging tape for your specific application can reduce product damage, decrease material waste, and increase efficiency. Corrugated cardboard boxes sealed with the proper tape maintain integrity during transport. Various factors go into the consideration process such as application method, content weight, environmental factors, distribution conditions, tape quality and grade, and adhesion surface/substrate. Using the wrong tape can be a costly mistake, so we've put together this guide to help you select the best tape for your needs.

Understanding the Different Types of Carton Sealing Tape

Carton sealing tape comes in various widths, lengths, thicknesses, materials, and strengths, and it is important to select one that will properly seal your boxes.

Length & Width

Sealing boxes with one strip of tape instead of multiple is always better. If you are using two strips of 2-inch tape, using 3-inch tape instead can save time and money. Hand carton sealing tape typically comes in 55-yard or 110-yard rolls. Machine carton sealing tape ranges from 1000-2000 yards in length.

We typically recommend using 3" tape for boxes over 16" wide. You may also want to consider a 3" tape if you are using 2 strips of 2" tape to seal your boxes.

Tensile Strength & Elongation

Tensile strength is the force required to break a tape and elongation is the percentage a tape can be stretched just before breaking. Investing in tape with high tensile strength and elongation allows for a more productive taping process.

Adhesives

Natural rubber adhesives are very flexible, even in low temperatures as low as 0°F. Appears brown in color, but is clear. 

Hot melt tape, also known as synthetic rubber, has quick stick bonding and long-lasting adhesive properties for packing overstuffed cartons or boxes made of high recycled content. Provides a more consistent seal so is used in most shipping situations.

Acrylic tape provides environmental resistance and has a faster setting time, making it ideal for long-term storage in varying temperatures and lightweight box sealing.

Thickness

The weight and dimensions of a box help determine the mil thickness of box sealing tape that is needed. The typical rule is that the heavier and larger the box, the thicker the tape will be needed. Additionally, tapes with a thickness between 1.6 mil and 1.9 mil are designed to be economical while still providing great performance.

Tips for Proper Tape Application

Proper tape application is essential for sealing boxes. Whether you are hand sealing or using a case sealer, use these tips to ensure proper sealing. 

Hand Sealing

1. Make sure the tape is properly positioned and ready for unwinding.
2. While applying the tape, maintain tension on the tape by gently pulling it tight as you move along.
3. Ensure that the tape extends across the entire seam or edge being sealed to provide full coverage and reinforcement.

Machine Sealing

1. Make sure the tape is properly mounted on the tape head with proper core tension, centered on the rollers, and in good tape blade condition.
2. Adjust the settings of the case sealer to match the dimensions of the boxes.
3. Verify tape placement on the carton and adjust if needed.
