Food packaging today is so much more than just protecting the individual product. It is true that the most important function, from the moment of packaging throughout transport, storage and retail, is to ensure that the contents arrive in private households in one piece. But design and material also have a large influence on buying decisions, because more and more people want food that comes in a more sustainable package.
Without any packaging, however, most foods cannot be transported, stored or sold and in their unpackaged state they would prematurely spoil. The protective wrapping keeps harmful influences like light, oxygen or humidity away and prevents soiling or damage. An extended shelf-life is a meaningful contribution to reducing food waste.
