Packaging
Packaging plays its protective role in various ways. It was originally used to protect foodstuffs from natural hazards and help prevent them from deteriorating. With the rise of commercial society, packaging became portable. The industrialisation and mechanisation of food manufacturing in the 19th century sped up its development and production. In the 20th century, new materials (PVC, PET) were added to the long list of natural materials, such as wood, tinplate and aluminium.
