There's Plastic and There's Plastic

Much of plastic food packaging is reportedly non-recyclable according to at least some local authorities (https://www.bbc.com/news/science-environment-45058971?intlink_from_url=https://www.bbc.com/news/topics/c6lpgw300llt/plastic-pollution&link_location=live-reporting-story). For example, yoghourt pots are generally incinerated (hopefully with the use of carbon-capture technologies) and you get an occasional weirdness such as plastic bottles being recycled but not their tops. Black food trays are also problematic as they are not identified by some automated sorting systems. As there is a public appetite to reduce plastic pollution, I  think that is largely up to food producers and supermarkets to try to ensure that food packaging is a) necessary and b) if necessary, recyclable. I think it is a bit much to blame cash-strapped local authorities for confusing things by their having a plethora of systems for recycling.
