  • Application

    Available until stock is depleted. Limited quantities.
    Bag stiffeners add another level of protection when storing or displaying photos, prints, postcards, magazines, and documents in crystal clear or poly bags. They protect corners and help prevent bending during handling. They are especially useful for storing thinner paper items like letters and other ephemera.

  • Features

    We offer high-quality, archival bag stiffeners in a wide range of sizes made from our acid- and lignin-free 40 pt. Tan ArchivalGrade™ boxboard. If you don't see the size you need we can cut something down to size.

    Available until stock is depleted. Limited quantities.

    Please visit the Board and Paper section of our website for alternative bag stiffeners such as 14 pt. white card stock and acid-free foamboard.
