Archival Envelopes Perma/Dur® Buffered | 8 sizes | Up to 292 x 381mm

Archival envelopes made of PAT passed paper stock. Our archival envelopes are an excellent acid-free and lignin-free storage enclosure for all types of photos, documents, clippings etc.

  • Buffered with approximately 3% calcium carbonate for protection from migrant acidity
  • Each is constructed using a neutral pH adhesive and includes an un-gummed flap to help keep out dust and light.
  • PAT test passed (Photographic Activity Test)

We're upgrading this range

We have eliminated the centre seam which could mark the contents if too much pressure or weight is applied. Instead we have incorporated two side seams that are not only safer, but provide more even stacking and filing in large groups. No adhesive on flap.


We're upgrading these envelopes from 120gsm to 200gsm PAT tested paper. Specification will depend upon size. Eventually all stock will be made from the upgraded 200gsm material.
