Compared to a label, a sleeve gives you more space for designs and, if necessary, more scope for appealing to a variety of target groups in multiple languages. A sleeve is like a second skin. It takes on the form of the packaging in its entirety, whereas alternatives such as labelling and printing directly onto the packaging has their limitations. If desired, windows can be incorporated into the artwork to make the packaged product visible. Sleeves are also scratch-resistant because they are printed on the inside.
