What is a wrapping scheme?
Basically, the winding scheme differs between outer winding and inner winding. In the case of outside winding, the label is on the outside, and in the case of inside winding, it is on the inside of the carrier film.
It is also important in which direction the printed image is placed on the label. Whether the label is portrait or landscape depends on the length and width of the labels. The label on the liner may come off the roll foot or head first. Labels stuck vertically on liner may come off the roll with the beginning or end of the word first.
