No, in this post I like to highlight the innovative creations of Kangaroo-packages (I like this word as it gives an exact definition of the matter), where the one product belongs or depends on the other product and brought together to form one product to serve a mutual goal.
Without doubt packaging history shows early examples of the Dual-, Two-in-One-, Twin- or Kangaroo-packaging. I remember, in the sixties of the last century being the beginning of packaging development in Europe after World War II, the tin packaging of Struik Conserven (in these days Struik Foods Europe) for the first experiments with complete ready-to-eat meals. Struik already had a reputation for its innovations in product and packaging. The one-litre tin had a “double bottom”, as the rice or something similar (I am not sure about it anymore) could be reached by opening one side and the prepared sauce by opening the other side. Two compartments in one tin, requiring the customer to open both sides.
As young packaging engineer I thought it was a remarkable innovation. It was primitive, in today’s terms, but then with such a limited choice of material and technology available, it was tremendous. At that time Struik used the same argument, Conagra is using (see later in this post) today: Separately prepared and packed products maintain their integrity in flavour, colour and nutrition values.
It took me years before I discovered another real dual of kangaroo packaging and I always wondered why, particularly, the food industry did not explore this innovative solution for quality and flavour with all the technology advances in materials available at this moment.
My chronologic overview starts in 2006 without having the arrogance to be complete.
