Factors that Affect Pressure Sensitive Label Adhesion

According to Freedonia, U.S. label demand will rise 3.8% annually to $19.7 billion by 2019. Labels, pressure sensitive labels in particular, are used in a range of markets and applications and fulfill different functions. For instance, a label may need to be permanent or easily removable, depending on certain application criteria.

As a result, adhesives play an important role in a label’s functionality and purpose. Learn about the top three factors to consider that can impact adhesion when selecting a pressure sensitive label adhesive.

Surface Condition

An application’s surface condition can impact a pressure sensitive label adhesive’s ability to adhere properly. For example:

  • Texture: surface may be smooth or rough
  • Contour: surface may be flat or curved
  • Contaminants: coatings, water, slip agents, etc. may be present

It’s also important to consider the surface energy of the substrate. Understanding the application’s surface condition prior to pressure sensitive adhesive selection can ensure an adhesive is chosen that can successfully adhere to it.

Environmental Conditions 

It’s a good idea to note the type of environmental conditions the label will be exposed to prior to adhesive selection. These include:

  • UV light
  • Humidity
  • Temperature extremes

For a label to function properly, the adhesive must be able to withstand the necessary environmental conditions it will be exposed to throughout all aspects of the label’s life.

Application Conditions

It’s also important to consider pressure sensitive label application conditions in order to determine an adhesive’s success. For example, consistent, even pressure must be applied throughout the label. Additionally, consider the application’s temperature and humidity levels.

An adhesive must be able to withstand application conditions in order to form a successful bond.
