Why is the chocolate wrapped in aluminium/plastic?

The Change Chocolate is in aluminium, the organic version is in plastic. Both materials have their advantages and disadvantages. We are aware of this and are not yet satisfied with either packaging. We have been dealing with the question of a satisfactory solution for food-safe packaging for a long time – we always have to keep food regulations in mind. That doesn’t make it any easier to find a suitable alternative to conventional packaging. We are very grateful for tips and experiences.
