At a case quantity of 100 units, this mailer is suited for mailrooms, print shops, photography studios, and businesses with regular flat-document shipping needs. Its lightweight construction helps keep postage costs low while maintaining protection throughout the shipping process.
The RM4W stayflat mailer is used wherever rigid, lightweight protection is needed for flat shipments. Typical applications include mailing prints, certificates, contracts, photographs, and similar documents that cannot be folded or rolled. This mailer is appropriate for both internal distribution and outbound customer shipments in commercial and light industrial settings. It is sold in a case of 100 units, making it practical for operations with moderate to high-volume mailing needs.
Designed as an OEM-style equivalent to part number S-1198. Suitable for standard flat-document mailing applications requiring rigid chipboard mailers with tab lock closures.
No tools are required to assemble or seal this mailer. Insert contents flat, fold the tab lock closure fully to secure the envelope, and verify the closure is seated before labeling for shipment. Handle cases with care to avoid compression damage to the chipboard stock prior to use.
