White Flat Mailers are designed to help protect documents, photos, artwork, prints, certificates, and other flat items from bending, creasing, and edge damage during shipping or transport. Made with sturdy chipboard construction, these mailers provide reliable edge, impact, and beam strength while keeping shipments lightweight and easy to handle. A self-seal, tamper-evident closure with paper-release liner and tear strip makes packing simple and opening convenient for the recipient.
