Applying carton sealing tape
When applying carton sealing tape, it is important to remember the following things: Make sure roller of dispenser is out/contacting the box. Remember, this is pressure sensitive tape and the tape requires pressure to stick properly.
Do not stretch tape. Stretched tape will begin to curl on the ends. Overlapping tape on top of other tape is usually a waste of time and tape. Maximize surface area of adhesive by going from multiple strips of 2" to one strip of 3" tape.
