Self adhesive labels come in all shapes, sizes and colours. They are used for a wide array of purposes, ranging from product pricing and identification to children’s sticker books. Different applications require the use different types of self-adhesive labels. Consider some of the most common types of self-adhesive stickers and their general properties:
Permanent adhesives are used when a label is to be placed and no subsequent removal is planned. Generally, these labels require the use of a solvent for total removal and removal will often tear the printed stock atop the adhesive. These are least expensive labels to produce.
Semi-permanent self adhesive labels use a glue that allows for repositioning of the label for a period of time after application. Eventually (usually within two or three days) the adhesive sets and becomes permanent.
Other applications necessitate the use of a label that can easily be removed without leaving residue on the area to which it was applied and/or without tearing the label’s stock. These are termed removable self-adhesive labels. They adhere well enough to stay in place during normal use and handling, but can still be removed with a simple pull.
Special situations call for special labels. An example of this is the freezer permanent label. These labels feature a special adhesive designed to remain in place even during exposure to extreme temperatures. Standard glues will often fail to adhere in these circumstances.
