Plastic meat trays (N8 Crouch End)

I don't eat meat so can't use my own rubbish so requesting on here.
I'm after those plastic trays meat comes in in supermarkets.
They're generally ribbed to catch the blood but don't have holes (which is why I want them).
Could someone save me a whole load, please?
All shapes and sizes; just not holes to leak liquid.
Please rinse first though....
Thank you for reading.
