plural of Papier
<div>In `DW's course` they said that `das Papier` has no plural form, however I've seen many dictionaries that use `die Papiere` as the plural of it.</div><div><br></div><div>I'm really confused now</div>

<div>@Ammar „die Papiere“ is formal for documents.“das Papier“ is just a blank or unimportant paper.Then you say „das Papier“ even if there are many of them.</div>

<div>The word "Papier" meaning the material to write on is an uncountable singular-only word. You can talk about "ein Blatt  Papier", "100 Seiten Papier", "3 Tonnen Papier", always in the singular form. </div><div><br></div><div>The plural word "Papiere" always has the meaning of "documents". </div>

<div>it‘s „die Papiere“ when you have several different papers. But its das „Papier“ if it is one single piece of paper.</div>

<div>@jessica</div><div>Why `DW` is saying that different papers can be refered using `das Papier` too? Is it a mistake?</div>
