Stayflats Plus® White Self-Seal Mailers in the 17 x 21 inch size deliver built-in rigidity through lightweight chipboard construction, eliminating the need for added stiffeners or inserts. The self-sealing peel-and-seal adhesive strip closes securely without tape, and a pull-tab tear strip gives recipients a clean, tool-free opening experience.
These mailers suit e-commerce retailers, print shops, photographers, and corporate mail rooms shipping large-format flat content — including posters, artwork, architectural drawings, presentation materials, and unframed prints — where arriving undamaged and uncreased is essential.
Each mailer measures 17 by 21 inches and is constructed from chipboard that keeps unit weight low while maintaining a flat profile throughout transit. The white exterior accepts branding or labeling cleanly. Cases contain 100 mailers and ship via parcel carrier.
