Bsc Preferred RM1K Stayflat Chipboard Mailer 100/CS

Product Description

The BSC PREFERRED RM1K is a stayflat chipboard mailer designed to protect photos, documents, and flat materials during shipping and handling. Manufactured from 0.028-inch kraft chipboard, the rigid construction eliminates the need for additional stiffeners inside the envelope. A peel-and-seal closure secures the contents without tape, and a pull-tab tear strip allows recipients to open the mailer cleanly without tools. Sold in cases of 100 units, the RM1K is suited for mailrooms, print shops, photography studios, and any operation sending flat, damage-sensitive materials in volume.

The RM1K stayflat mailer is used in both commercial and light-industrial shipping environments where rigid protection for flat contents is required. Typical applications include mailing printed artwork, legal documents, photographs, certificates, and promotional materials. The lightweight chipboard construction helps keep individual package weight low, which supports postage cost control on high-volume outbound shipments. Each case contains 100 mailers, making it practical for operations that process regular outbound mail runs.
