How Solvent-Free Adhesives are Changing Flexible Packaging

Environmental regulations continue to increase, spurring the growth and development of solvent-free adhesives. As cited in Food and Beverage News, these new adhesives are changing the flexible packaging industry. Let’s take a look at how:

 What are Solvent-Free Adhesives?

Adhesives are deemed solvent-free if they contain no more than 5% solvent in their formulations. They offer the following advantages:

  • Reduced health risks
  • Improved environmental footprint
  • Flexible processing time
  • High initial strength

Two Main Types of Solvent-Free Adhesives Include:

  • Water-based adhesives: the largest group of solvent-free technologies
    • Tend to have higher surface energies than solvent-based adhesives
    • Improve adhesive properties for a given application
  • Hot melt adhesives: the fastest growing class of solvent-free technologies
    • Offer versatility and good cost in use
    • Have a rapid set time

How Solvent-Free Adhesives Benefit Flexible Packaging:

The Adhesive and Sealant Council cites the solvent-free adhesives have impacted the flexible packaging market in the following ways:

  • Packages made with these adhesives are often lighter and take up less shelf space for display, storage and shipping.
  • Solvent-free adhesives provide good clarity, temperature resistance and a humidity barrier.
  • They are used to join layers of film, foils or paper in high-performance packaging.
