Description

The Stayflats® Express Mailer is a rigid flat mailer manufactured from white chipboard, providing firm protection for flat contents without requiring separate stiffeners. The side-loading design allows easy insertion and retrieval while keeping contents flat throughout transit.

These mailers suit e-commerce fulfillment, print shops, legal and financial offices, photo labs, and professional correspondence operations that ship documents, certificates, photos, and flat media on a regular basis. The lightweight chipboard construction helps manage postage and carrier costs.

The peel-and-seal adhesive strip delivers a secure, tamper-evident closure, and the pull-tab tear strip lets recipients open the mailer cleanly without tools. Each case contains 250 mailers, supporting consistent flat-mail volume for operations that reorder in bulk.
