Stiffener Boards for Paper & Polyester Envelopes

Keep envelopes upright in storage boxes while preventing excessive bending or twisting during handling. Lightweight, yet rigid, stiffeners will provide the added structural support for old, fragile, or brittle documents, pamphlets and photos when placed in envelopes. Manufactured from 10 pt. tan acid and lignin-free buffered folder stock (8.5pH), stiffeners are sized to fit the most popular size envelopes. Custom size stiffeners are available upon request; please contact our Customer Service Department for details. PASSES STANDARD PHOTO ACTIVITY TEST (P.A.T.)
