Direction of unwinding
Inside : the side of the label is inside the roll.
Outside : The side of the label is outside the roll.
Layout of labels
The labels are arranged on a continuous sheet folded at the same interval. All label sheets are bundled in boxes.
Perforation and slit
Perforation : A series of separate, tiny cuts on the top of the label that do not pierce the label backing paper. It should be noted that the peeling of the label cut by perforation works less well than the smooth cut label when we want to fold or tear the label.
Slit : A smooth, continuous cut across the top of the label that does not cut through the label backing paper. Unlike punch labels, slot labels can be removed like individual smaller labels.
