Resin platters

Can we use resin platters if they were used during the year

Were they used with hot food? If yes, may be a problem (need more details), if only used for cold, as long as it’s clean

What details do you need?

I’m not sure if it absorbs… Is it porous? We generally say had plastics aren’t Boleah.
I’m going to say err to the side of caution for now and maybe we can research in the future.
