Peel-Open Containers

The integration of peel-opening features into package and product designs continues to grow.  Improvements in adhesives and bonding technologies have made it more practical for food, consumer, and medical manufacturers to reliably incorporate these types of features into their packages.

In support of this process, Stress Engineering has developed analytical methods to estimate peel forces as a function of package geometry, bond characteristics, and film material properties. These new methods are particularly useful in understanding and optimizing the trade-offs that are inherent in peel-open packaging systems. They can also help avoid one of the most common problems - the film tearing prior to complete opening of the package.

Based on our unique understanding of the mechanics of peel-open packaging, Stress Engineering routinely helps clients:

  • Fine-tune individual design components
  • Establish bounds on possible geometries
  • Define essential characteristics of package constituents
