Four Flap Enclosures – Unbuffered PAT Passed

Unbuffered four flap enclosures are an excellent choice for the long term storage of standard negative film, glass plate negatives, prints and more.

The enclosures are made of PAT passed archival quality 120gsm paper which is an acid free and lignin-free paper of high alpha cellulose content with excellent folding properties.

When storing negatives the design of the enclosure allows the negative to be encased on all four sides assuring the uniform pressure which is so important. The four flap design allows the envelope to be opened completely, providing full uninhibited access to the contents, reducing the risk of handling damage. Please note: 727-13258 has two half width flaps and two full width flaps.
