How best to tape up a slotted box with an adhesive tape

When taping up slotted boxed, overlap the tape to 1/3 of the side of the box (12 cm at minimum), in case of strong boxes prolong the overlap proportionally, the overlap and the above-mentioned pressure in application to the cardboard and subsequent smoothing by hand over the entire surface of the tape will prevent natural pressures in the box to cause its unsticking.

They best taping up is when the adhesive tape is applied all around the box (if, of course, the size and weight of the box permits).
