How are the two types of packaging tape dispenser?
Sealing Cartons with Pressure-Sensitive Tape
Plastic pressure-sensitive tape is typically applied using a hand-held tape gun. First, the user finds the leading edge of the tape roll. Then they press that section of tape to the side of the carton and pull the tape gun and along the seam to be sealed while applying constant pressure. That pressure is critical, as the tape as no ability to form a bond other than through the force applied by the user. The tape is then pressed down on the carton.
Pressure-sensitive tape typically requires multiple strips to close a package for shipping, so the process is repeated. A user may also choose to apply tape to additional seams, in which case they must rotate the package to get the proper angle for the use of the tape gun. Overall, it is a very physical and often repetitive process to seal a single carton.
Sealing Cartons with Water-Activated Tape
Reinforced packing tape or kraft paper tape is applied using a manual or electric paper tape dispenser. These tape machines distribute the appropriate amount of moisture to activate the adhesive and then dispense pre-cut strips of user-specified length. The tape is placed on seams by hand and can be applied with light pressure since the adhesive penetrates the carton surface and forms a strong bond with it.
That bond is created quickly, and the package is safely and securely sealed. Typically, only one strip of paper packing tape is needed. If additional pieces are desired for added security on the sides of the carton (forming an “H” pattern), the process is repeated. Physical manipulation of the carton in order to apply the tape is minimal.
