How to seal a box
The simplest and fastest way to seal a cardboard box is to use a hand tape dispenser.
A tape dispenser allows the packing tape to flow through the machine and cut the tape to the required length.
The most secure way to seal a box is the ‘H’ seal method.
The H seal method allows for all the flaps of a cardboard box to be sealed, giving extra protection.
The H seal method also shows a high level of tamper evidence as there is more tape to remove.
Below is our easy to use guide on how best to seal a cardboard box.
Using a tape dispenser, start from the side of the cardboard box and pull the tape dispenser back and over the top of the box to seal the two flaps.
Continue to pull the tape dispenser back across the top of the cardboard box and allow a further few inches of tape to follow down the side of the box.
Pull the tape dispenser down so the blade will cut the tape at the required point.
Use the tape dispenser to seal the edges of the cardboard box in the same way as the top but allow an overhang of tape.
Fold over the overhang of tape to the side of the cardboard box.
Repeat on the other side and seal the bottom of the box as previously done. When you have finished, your cardboard box will be sealed on all sides, displaying an H on the top and bottom of your box.
