At Label Planet, we supply a wide range of labels, which can broadly be divided into two categories: Permanent Labels and Removable Labels – which, you will undoubtedly not be surprised to learn, are made with permanent adhesives and removable adhesives respectively. This post takes a closer look at the labels that fall into the first category (Permanent Labels) and the adhesives used to make them stick.
Generally speaking, a permanent adhesive is any adhesive that is designed to create a strong adhesive bond that is difficult to break. This does NOT mean that permanent adhesives are 100% permanent; any label held in place with a permanent adhesive can be removed if an individual is determined enough to do so – permanent adhesives are simply designed to make the removal of a label as difficult as possible (which means that they will usually leave behind adhesive residue and may damage the surface that they were applied to when they are removed).
Permanent adhesives typically offer good initial tack (this is the strength of the adhesive bond that is created at the moment an adhesive is applied to a surface) and good ultimate tack (this is the strength of the adhesive bond that is formed once the adhesive has completely strengthened and set).
SELF-ADHESIVE PERMANENT ADHESIVES
At Label Planet, all of our labels are “self-adhesive”/“pressure sensitive” labels (made with self-adhesive or pressure sensitive adhesives); this simply means that these labels require only the pressure of a finger or hand to adhere to a surface. Other adhesives may require the presence of another substance or specific conditions to form an adhesive bond (e.g. water sensitive adhesives require the presence of water to initiate a chemical reaction that leads to the formation of an adhesive bond, while holt melt adhesives must be melted and allowed to cool back into a solid to create an adhesive bond). Pressure sensitive adhesives, however, are tacky (sticky) in their dry form at room temperature and are applied using only the pressure of a finger or hand.
DIFFERENT STRENGTHS OF SELF-ADHESIVE PERMANENT ADHESIVES
Permanent adhesives are available in a range of adhesive strengths; standard permanent adhesives, for example, will be able to form a good adhesive bond between a general range of surface types and materials, while stronger permanent adhesives (sometimes called High Tack Adhesives) will be able to form a strong adhesive bond between a wide range of surface types and materials – including curved surfaces and unusual materials such as wood, plastics, and metals.
Permanent adhesives may also be designed to provide better adhesive strength under more challenging or unusual environmental conditions, such as Marine Adhesives (designed to create a permanent adhesive bond that can survive exposure to or immersion in water) and Freezer Adhesives (designed to create a permanent adhesive bond that can survive in freezing conditions).
