There are two basic types of self adhesive labels: permanent and removable. Each type of adhesive is made from a variety of glues depending on the conditions the label will have to endure, the length of time it is required and the environment or conditions of storage.
Self Adhesive labels are usually coated with an acrylic, rubber or water-based glue. Sticky labels can either be applied permanently or temporally.
There are four major types of label adhesive
1)High tack label adhesive is used for labels that have to stick permanently to rough surfaces, or shaped structures. A permanent label adhesive should only be used if the label is not going to be removed. The label and adhesive can only be removed by using a solvent.
2)A peelable label adhesive is suitable when a label is temporary and will need to be removed or replaced. The label will peel off and no adhesive residue will remain. These self adhesive labels are also know as repositionable, or removable labels.
3)Freezer adhesives are used on freezer or refrigerator labels. The label adhesive will not crack or peel under the extreme cold, damp conditions.
4)Static cling labels are usually plastic and can cling to smooth surfaces using a static charge only. They are easily repositioned or removed without leaving a residue.
