I am looking for an envelope with the same material as the Dell enveloppes. Anyone an idea where I can get them in Europe and what kind of material is used for this?
I don't know if the Dell empty cartridge retour envelopes are used worldwide but here is a discription how they are in Belgium:
Size: 12cm x 19cm (4.72"x 7,48")
Colour: Blanco with blue prints
Enveloppes are waterproof (I tested it with water)
Looks like a kind of paper with some fiber in it. Hower it can burn and it did not melt by a fire, I am not certain it is paper.
You can print on it with an inkjet printer
and it holds the ink.
There is also written "The process chlorine-free(PCF) paper in this envelope incorporates 20% post-consumer fiber"
Hope this helps. Already thanks for your help!
