When is tissue paper not tissue paper?

I recently bought, on-line, some fancy Tissue paper made by a specialist Italian company called Caspari. Now although it is labelled Tissue paper , it is in fact thin printed wrapping paper.

My understanding of tissue paper js the very fine easily crushable paper used for an initial protective wrap of fragile and delicate items, not wrapping paper which, even when thin is altogether more robust.

Are there several types of tissue paper? Caspari is an Italian firm so although the stuff I bought us labelled in English. maybe they define it differently?

What I want is the very thin stuff not conventional thin wrapping paper.
