Bsc Preferred RM129 Stayflat Chipboard Mailer 100/case

Product Description

The BSC PREFERRED RM129 is a stayflat chipboard mailer designed to protect photos, documents, and flat materials during shipping and handling. Constructed from white chipboard, this side-loading mailer provides rigid protection without requiring additional stiffeners. The peel-and-seal closure secures contents quickly, and a pull-tab tear strip allows recipients to open the mailer cleanly. Each case contains 100 mailers. The lightweight chipboard construction helps keep package weight low, which can reduce postage costs compared to heavier rigid alternatives. This mailer suits shipping and mailroom operations where flat, damage-sensitive materials need consistent protection.

The RM129 is suited for businesses, print shops, photographers, offices, and fulfillment operations that regularly ship documents, prints, certificates, or photos. The side-loading design allows easy insertion and retrieval of flat items without bending or folding. Sold in cases of 100, the RM129 supports higher-volume mailing operations. This equivalent replacement is also referenced as part number S-3828.

Installation Notes

No tools are required to prepare or seal these mailers.

Store unused mailers flat in a dry environment to prevent warping of the chipboard stock before use.
