Opaque Envelopes – U-style
Premium-quality photographic archival envelopes with gumming on the exterior for storage of prints, negatives, microfiches and glass plates. The envelopes are made of ageing-resistant photographic archival paper with the opening located on the long side of the envelope. They are available buffered or unbuffered, and in white or natural white. Gumming on the outside of the envelope ensures smooth interior surfaces. The stored object has no contact with the gummed flap and is safe from any rubbing or chafing that may otherwise be caused by paper edges located inside the envelope. Paper and adhesive have passed the Photographic Activity Test (PAT) according to ISO 18916.
