8. Can packaging and energy usage be reduced without compromising the protection it gives to the food?

Here are four examples

In 1970, the weight of a metal can for baked beans was 68.9 g.
In 1990 the same size can weighed 56.6 g.

In 1950, a glass milk bottle weighed 397 g. In 1990, the same
size bottle weighed 245g.

In 1983 a 1.5 litre PET plastic soft drinks bottle weighed 66 g.
In 1990, the weight has been reduced to 42 g.

In 1950 a tinplate beer can weighed 91 g. In 1990 an aluminium
beer can weighed only 17 g, and was fully recoverable for recycling.
