The BSC PREFERRED RM19SS is a side-loading stayflat mailer designed to protect photos, documents, and flat media during shipping and handling. Manufactured from white chipboard, these mailers provide rigid support without requiring additional stiffeners. The peel-and-seal closure speeds up packing operations, while the pull-tab tear strip allows recipients to open the mailer cleanly and quickly. Sold in cases of 200 units, this product is suited for shipping departments, print labs, and fulfillment operations that send flat materials at volume.
These mailers are a practical solution for businesses and trade professionals who regularly ship photos, certificates, contracts, architectural drawings, or other flat documents that must arrive undamaged. The side-loading design makes inserting and retrieving contents faster than top-loading alternatives, reducing handling time on the packing line. The lightweight chipboard construction helps keep package weight low, which can reduce postage costs across high-volume shipments.
Designed as a stayflat mailer for shipping photos, documents, and flat media; equivalent to part number S-2664.
No tools required for use. Insert contents through the side-loading opening before removing the peel-and-seal liner and pressing the flap firmly to close. Store unused mailers flat in a dry environment to prevent warping of the chipboard. Follow carrier guidelines for maximum insert weight and dimensions to ensure postage accuracy.
