Problems are mixed plastics and like you wrote that it is not economically feasible under current economic conditions.
Reality is that probably your common food packaging should cost 3-10x as much as it does currently, so all plastic packaged food would increase in price by 20-30% or so. (The numbers are just very rough estimates)
The issue is not the recycling, but the lobbying to not create the environment, where it becomes feasible, but plastic packaging becomes less interesting and alternatives become more viable.
Plastic recycling can be feasible.
