Why is food packaging important?

Even though this technical design drawing represents a product that we associate with “fun food”- this image shows evidence of important science and industrial design taking place. Industrial designers and food chemists work closely tighter to ensure our food is packaged in the best possible way.

This drawing was made in the 1960’s. What is it ?
Why would the food producer chose this kind of packaging?
Why would the food transport company prefer this kind of packaging?
Why would the food consumer prefer the food inside, compared to other brands, if away on a camping trip?

Looking forward to your answers,
