So, it is important to emphasize the pictorial message in the opening instructions, because in contrast to written messages, they have a more universal character and facilitate the comprehension , especially for people with low level of education.
The absence of coherent instructions or the lack of comprehension will cause users to use more and more aggressive ways to open the packagings culminating in the use of tools and/or sharp objects that can cause serious injury.
Therefore, comply with regulations and standards is not enough. The designers and the industry should take into account that consumers rarely read the opening instructions and therefore they should ensure that the packaging design is intuitive and accessible.
