As much as I try to avoid bringing plastic packaging into the house, it's nigh on impossible to avoid ALL plastic, and only the hard plastics can go into the council recycling. What do you do with all the soft plastic - e.g. film lids, cheese wrappers, biscuit packets?
The supermarkets have long had bins where you could put used carrier bags, and more and more bags are now marked that they can be recycled alongside the carriers - loaf bags, frozen food bags and the like.
Sainsbury's and Co-Op have now expanded their soft plastics collection to include things like biscuit/confectionery wrappers, film lids (e.g. from grape punnets) and more.
Sainsbury's: www.about.sainsburys.co.uk/sustainability/plan-for-better/our-stories/2021/flexible-plastics. The page lists what they will take and a link to a list of 500 participating stores. Although, my local store is NOT on that list but they have attached to the bin used to collect carrier bags a list of what else they will take, which is pretty much the full list. So even if your local store isn't on that 500-store list, it's still worth checking if they are taking it anyway.
Co-Op: "Clean it. Scrunch it. Co-op it." www.coop.co.uk/environment/soft-plastics There are links in that page to which packaging they will take, and which stores will take it (1500 stores involved so should be one nearish).
I think Tesco may also be doing this now, but haven't checked.
Also, it's worth checking if anyone near you Terracycles plastics - www.terracycle.co.uk. Basically this is a collection of sponsored plastic collections, e.g. Walkers sponsors the collection of crisp packets and KP the collection of nut packets. It's quite a range of collections, from food packaging to toothbrushes and a pretty wide range of the hard-to-avoid plastics.
Terracycle pays a small amount to the people who accept the plastics and forward it to them in bulk, so often this is done as a way of raising funds for charities. The Terracycle website has maps showing you where you can drop off what plastics, plus the people who do the collections often have Facebook groups you can join. For example, my local group accept plastics for about fifteen different schemes and you can ask questions if you're not sure if a particular item is acceptable.
I'm now putting to one side most of the soft plastic packaging to be Terracycled, and what remains can mostly go to Sainsbury's and the Co-op. Very little is going into the bin/landfill.
