Did you know that hot melt adhesives have been around for nearly 76 years? In 1940, Paul Cope, a chemical and packaging engineer at Proctor and Gamble, invented the hot melt as an improvement to water-based adhesives in packaging that were failing in humid climates.
Since the invention of the hot melt, we now have a wider selection to choose from: EVAs, PURs, metallocenes, polyamides and more. Then there are pressure sensitive adhesive tapes (PSAs). While the first group of liquid hot melts requires heat to activate, PSAs are applied at room temperature.
Heat aside; there are several key differences between PSA tapes and liquid hot melt adhesives. We compared the two in four major categories, which include:
- Ease of use
Take a look at the infographic below to see how PSAs compare:
Many businesses integrating a hot melt to increase the efficiency of their process could benefit from considering a pressure sensitive adhesive. Some key factors you may review include production volume, safety concerns and customization needs. We always recommend working with your supplier to determine if a PSA product would be the best option for your process.
