From 1840, the early steam age, until today waxed paper, tin cans and glass bottles are used.
From 1880, the late steam age, until today add early plastics like celluloid and rubber. Cereals in cardboard boxes. Corrugated boxes used for shipping.
From 1920, the early electric age, until today add thermoplastics used in vacuum formed packages.
By 1960, the late electric age, there are additional plastics in use.
Today we still use all methods of packaging food.
