Exactly. Supermarket have added a lot of plastic packaging supposedly for our 'convenience', like adding separator sheets between slices of cheese, or strawberries in a plastic container instead of the cardboard they used to be packaged with (so you can judge the quality better?). Or the convenience of the cashier, so they can see you packed the right vegetables in the sack. And probably they use plastics instead of paper because its cheaper, and they can scrape a penny off the price. A lot of the power on what packaging is used is still in the consumer's hands, though. Just don't buy those cookies that are individually wrapped.
