Can someone please let me know the differences between the Zurisack and the other black rubbish bags?

I live in Zurich and I have looked all over the intrenet and cannot find a concrete answer, such as:

1) What EXACTLY can/do you put in black bin bags?
2) What EXACTLY can/do you put in the Zurisacks?
3) If you put something not allowed in the Zurisack do you get fined?
4) If you put something not allowed in the black bin bags do you get fined?
5) If the answer is yes either to (3) or (4) how do you get fined, e.g. how do they find out it was you, if you do not throw away any receipts with your name on (which I never have done, or anything else with my name on).

Referrence to (1) and (2) above, what about normal household rubbish, e.g. milk cartons, meat packets, empty plastic soft drink bottles and other daily rubbish? In which bag do we have to thow them away? In the Zurisacks or in the black rubbish bags (which are sold in amples quantities in all supermarkets) ?
