  • Application

    These Open-End Envelopes were designed for the long-term storage of large format film and contact prints. Use in conjunction with Film Interleaving Folders or Side Lock Film Sleeves for safe handling and protection from dust and other pollutants, then store in one of our archival metal edge boxes.

    These envelopes can be used to archivally store other small, flat items in your collection as well.

    Please note that color of envelopes may vary from white to cream (pictured).

  • Features

    These envelopes are constructed with double edge seams. This design ensures that envelopes stack perpendicular rather than in a “fan” shape, which can occur with conventional envelopes. Seams are bonded with pH-neutral adhesive on the outside to provide a smooth inner surface. The open end has a 1/8 inch lip for easy access to contents. Constructed of heavyweight 7-point acid- and lignin-free card stock.

    NOTE: Do not use envelopes with center seams for archival storage. Pressure on the seam from adjoining files will usually fall in the center of the contents and over time may cause damage. Archival Methods does not offer any archival envelopes with center seams.
