Direct Thermal or Thermal Transfer Labels? 

Direct Thermal  No ribbon required Labels print only in black, unless they are preprinted with special thermo chromatic ink Labels have a shelf life of 1 year or less Labels not prone to sunlight or heat Labels not prone to friction or abuse 

Thermal Transfer  Requires a thermal transfer ribbon Labels can be printed in colors other than black Labels have a shelf-life of over 1 year Labels are subjected to heat or sunlight Labels are prone to abuse or surface friction 

To help you decide, consider the following questions: 
Will you ever need to print labels in colour? 
Do the labels have a shelf-life of over 1 year? 
Will you be printing high density bar codes taht require scanning? 
Will the labels be subjected to heat or sunlight? 
Will the labels be prone to abuse or surface friction? 
Will you be printing on a variety of different substrates (i.e. papers, films and foils)? 
If you answered 'yes' to any of the above questions then you should consider thermal transfer rather than direct thermal. 

Which Adhesive Is Right For Me?  Selecting an adhesive for labels seems like it should be as easy as just picking a label,  but there are actually a number of factors that should be considered to ensure the correct  adhesive for the long term. 

Which Adhesive? 
There are a number of different types of adhesives, each made with a variety of different materials. The most common are acrylic, rubber and water-based. 
1. Permanent adhesives are probably the most common type and designed to remain adhered after first contact. Water-based, rubber and acrylic adhesives are all used for permanent labels, however each have their limitations. Water-based adhesives, for example, should not be exposed to moist environments, while rubber adhesives break down when exposed to sunlight. Acrylic based adhesives are most useful for labels that need to withstand time and frequent handling. 
2. Peelable adhesives are designed to allow the label to be removed. However they may leave some residue, so for certain items they may not be suitable. 
3. Ultra-peelable adhesives are a good replacement for peelable labels that need to be applied to items that require labels to be easily removed. A weak adhesion means that if used incorrectly these labels may fall off. 
4. Freezer or frost fix adhesives are designed specifically to be used in extremely low temperatures. While conventional adhesives become ineffective, frost fix adhesives will still adhere at temperatures below -30°C, ideal for food products that require freezing. 
5.Static cling labels do not actually use a traditional adhesive, rather using static charge to stick to extremely smooth surfaces such as glass. 
6.High temperature adhesives are designed to withstand high temperatures for short periods, making them ideal for applications where high levels of heat resistance are required. 
Consider The Application 
1. Should the labels be permanent or removable? 
2. If permanent, how long are the labels going to need to stay on? 
3. What is the label being stuck to? 
4. Is the label going to be exposed to different physical environments or temperatures?

All our labels are *FDA approved, this is especially important when using TPN and Oncology labels *(The U.S. Food and Drug Administration (FDA) examines, tests, and approves a wide range of items for medical use, including drugs and medical appliances. In the simplest terms, “FDA approval” means that the FDA has decided the benefits of the approved item outweigh the potential risks for the item's planned use).
