Plastics are just pretty damn convenient materials. They're solid, cheap, can be made flexible or hard, don't rust, are easy to clean etc... Glass is heavy and breaks when dropped, metal is less heavy and only dents but it's more expensive than plastic. A lot of metal containers have an internal plastic lining simply so that food (and especially acidic food) doesn't react with the metal through direct contact.

Once in a while I'll see something about the history of food preservation and it's always funny because the more optimistic folks will point to a particular date and inventor as the birth of pasteurized canning. And then a more curmudgeonly person will sometimes point out that the tin from those cans would leach in and turn the food black. Not quite the victory people make it out to be. It was a bit later before they got the process to store food that people would eat.
