What is this paper type called?

[Dimis]

I looked up paper types online for half an hour… and gave up. Basically it's very convenient to use for protecting sharp tips when packing models. But… what is it called?!?

Thanks :-)

Try Googling packing foam sheets or packing foam rolls.

Actually i did get something that looks like it with "foam sheets". I thought the material was different. Thank you!

Air foam rolls.
