SAMPLING AND TESTING
Output of developing or optimising packaging is a sample or prototype. Depending on the scope of service, these are:
Work sample
The first phase is used to test the functional properties of the sample. It does not yet have all the required requirements in terms of quality of design or final material.
Presentation sample
The second phase is already made of the final material and serves for presentation to the customer. So far, however, it is still a prototype awaiting comments, not yet in mass production.
Test series sample
The third phase takes place after approval of the presentation sample and already contains all the details of the serial design.
