words fails me (or is it google)
pitch paper envelope
tar paper envelope
history of padded envelopes
antique envelope
bitumen folder.....
I know they exist, whatever they are called, there's a filing cabinet full of them from the 1950's in morewell.
They are yellow envelopes a bit wider than A5, opens on the long side with a flap, visible at seams padded layer is filled with a fibrous layer coated in a black shinny substance that looks like tar, and crackles a little as the envelope moves. All I can find out about is tar paper roofing material, envelopes padded with paper or bubble-wrap, plain non padded historic envelopes, and sound envelopes. Oh, and why manilla folders are called that.
oh well, it probably doesn't matter....
