So I always see these signs and numbers on plastic containers, what do they mean?

Someone else can tell you more… But I know that one is the type of plastic… “PP” = Polypropylene”. There are quite a few types of plastic and I think its printed on there for recycling purposes

I’m assuming another symbol could be batch numbers from the manufacturer.
I dont know the rest though
