How can that be? Let's look at the things we buy in a supermarket. Raw meat should be wrapped in an extra plastic bag to prevent blood leaking on to other products. Depending on how quickly shoppers get home, frozen goods will saturate and fall out of paper bags. Incidentally, paper uses more energy in production than plastic bags and gives off methane when it biodegrades. But probably the most important factor is that plastic bags have many uses for which there is simply no substitute.
