Can you recycle plastic bags?
Usually no
Yes, but never in your curbside bin. Plastic bags jam sorting machinery, so they have to go to a store drop-off bin instead — most large grocery chains have one near the entrance.
What you need to do
- Never put bags in the curbside bin, loose or full
- Never bag your recyclables — bagged material is often landfilled unopened
- For drop-off: clean, dry, and empty out receipts and crumbs
- Stuff everything into one bag so it stays together in the collection bin
Why the answer isn't simple
Three different questions hide inside "is this recyclable?" — and most pages only answer one of them.
Is the material recyclable? yes
What the stuff is made of, in principle.
Grocery bags and most stretchy plastic film are polyethylene, which is genuinely recyclable and has real end markets — composite decking and new film among them. Nothing about the plastic itself is the problem.

Will a sorting facility recover it? no
What actually happens on the line.
This is the whole problem, and it is mechanical rather than chemical. Sorting facilities call bags and film 'tanglers': they wrap around the spinning shafts and screens that separate paper from containers, and they keep wrapping until the line has to be stopped. Clearing them means a worker physically climbing into the machinery with a knife. A single facility can lose hours a day to it, and the cost runs into six or seven figures a year for a large city's programme.

Will your curbside program take it? rarely
Local policy, which is where answers diverge.
Effectively no US curbside programme accepts loose bags or film, and putting recyclables inside a tied bag is worse still — bagged material is often pulled off the line unopened, so the contents go to landfill even though every item in the bag was recyclable.
Where else it can go
Store drop-off
The route that actually works. Large grocery and retail chains keep a collection bin near the entrance, and the material goes to processors built to handle film without jamming. Bread bags, produce bags, bubble wrap, air pillows and case wrap all go in the same bin.
Must be clean, dry and free of food residue.
Reuse
Bin liners, pet waste, packing material. Reuse displaces a new bag one-for-one, which beats recycling on every measure.
Common mistakes
- Bagging recyclables 'to keep them tidy' — this is the single most costly recycling mistake, because it sends good material to landfill
- Assuming the recycling symbol on a bag means the curbside bin will take it
- Including crinkly film like cereal liners or crisp packets, which are a different plastic and are not accepted at drop-off
