Reduced strength


Strength and grip options are different with people suffering from musculoskeletal disorders (MSD) in their hands. The maximum strength when opening a packaging and the breadth of your grip will be smaller if you are suffering from dexterity disabilities. An English study (Specific anthropometric and strength data for people with dexterity disability, Consumer and Competition Policy Directorate) showed that persons with no physical ailments on an average have twice the strength when opening a jar with two hands, grip and pull of a 2 mm flap or a block as well as pull force for e.g. a ring in a can.


Variation in muscle strength

Generally there is great variation in the force people are able to transfer to a packaging. This is obviously also the case when we deal with people having physical ailments. It also means that there will be some people who are only able to transfer very little force. By basing the development of packaging on the force possessed by people with physical ailments you will make sure that the majority of people will be able to open the packaging without problems.
