The basic material of the envelopes is a 100% wood-free cellulose, with a pH value of 7.5 to 8; buffered with calcium carbonate; slightly moisture-resistant.
The paper is ICN1 certified, PAT approved and FSC certified:

Harmonica model:
A combination of a box and en envelope; made of 290 gsm acid-free board. Due to the special harmonica
fold, thicker objects (a stack of papers, magazines, booklets, etc.) that are too thick for a regular envelop,
can be archived easily and safe. The envelope can be used as single packaging and thus archived directly in
depot, or used as a secondary packaging for objects stored in an archive box, e.g. in the Amsterdam Box,
box code 169.
