Up here in Brisbane, and any other AUS council that hand-sorts the recyclables, we can only throw into a recycling bin, plastic that has the recycling/plastic number on it (1-7) somewhere on the actual plastic. Otherwise, the sorters don't know where to sort it, and it just goes back into 'general population' rubbish.

My Seaspray packaging didn't appear to have the plastic number on it, so for me, I have to throw it in the normal rubbish bin. For other areas, which recycles all plastics, it's a good thing, as it means the whole thing is now recyclable, provided you remove the new twist ties from the plastic before trashing it.
