Packaging and advertising were virtually unknown. Today packaging is a massive, lucrative industry and often it is the way the packaging looks that persuades the shopper to buy the product inside it.

It must also be protected against micro-organisms, chemicals, soil and insects.

Some shapes cannot be easily packaged, for example, certain vegetables. However, there are methods of getting around this problem. Suppliers of canned vegetables such as carrots have developed a particular type of plant that yields carrots that are straight and smaller than the normal variety. These fit into cans. Some products such as fruit juices and sausages need to be contained in packages that hold them together and are sealed to prevent spillage and loss.

The package will also contain important information including ingredients and ‘sell by date’.

A package should be designed to make it easy to transport, move and lift. A regular shaped package (such as a cuboid) can be stacked without too much space between each package being wasted. This means that more packages can be transported in a container of a lorry. Unusually shaped packages can lead to space being wasted and this can be costly if thousands of the same package are been transported.

In supermarkets and shops it must be possible to stack packages so that space is not wasted on the shelves. Lost space on shelves is looked up on a lost opportunity to sell to a customer. Also, the package must be designed in such a way that all the important information can be seen by a potential buyer, especially the product name. The next time you visit the supermarket look carefully at the shape of the packages. They are usually the same rectangular / cuboid shape. It is the selection of colours and shades that determine whether the product inside is regarded as a quality, sophisticated or cheap item. Often packages are stacked on top and alongside each other to reduce wasted space. The shape and form of the package determines how efficiently they can be stacked or stored.
