Flaps and bags


Use the calculator model to estimate what percentage of the target group in the Danish population will be able to open flaps and bags with the stated dimensions using a pincer grip. Try inserting different dimensions and forces. See the difference.


NB: Be sure only to use this calculation as a guideline when choosing dimension and opening force needed as the model is based on a limited set of data.


This is how you calculate how many people will be able to open

  1. Fill in the blanks with the length of flaps or the grip area for bags in cm and the mechanical force needed to open the packaging (see mechanical test).
  2. Read the percentage of women and men who are able to open the packaging depending on their age
