Scientific background for the basis of an international standard for easy-to-open packages - EASYOPENPACK 2006-2008 (NT TR 614)

NT TR 614

  • Various characteristics of food packages are nowadays good, including their safety aspects. However, a novel problem has arisen: how to open the package easily. This is a challenge not only to consumers with reduced hand function, but it is common for all of us to face every now and then difficulties in opening packages. But what makes it easy to open a package, and what are the most critical factors for consumers in opening packages?
