Studies on packaging accessibility are still incipient in Brazil. Many of these packagings can represent a challenge to users, whether due to non-informative labels, tricky tabs or seals, or even those that need strength to open. This paper brings a simple test to determine the necessary torque force to open PET bottles, and to predict the amount of users that could not open it. The findings suggest that a considerable amount of users could not open it or would have some difficulties to exert…

Rating Accessibility of Packaging: A Medical Packaging Example
TLDR
It was proposed to develop a methodology by which the relative performance of packaging could be assessed with respect to dexterity issues and a range of techniques were used to understand this problem.
Evaluation of the Accessibility of Selected Packaging by Comparison of Quantitative Measurements of the Opening Forces and Qualitative Surveys through Focus Group Studies
TLDR
The evaluation of a package was found to be only partly dependent on the required opening force but strongly influenced by various design factors and consumer's expectations as well as experiences.
State of the art of user packaging interaction (UPI)
User packaging interaction (UPI) has evolved in packaging research because of its importance to users, manufacturers, and designers. A great deal of work addressing problems and suggesting potential
