The 12-3/4 x 15" Kraft Self-Seal Stayflats Plus® Mailers deliver rigid, stay-flat protection for flat contents without requiring separate stiffeners or inserts. Each mailer is constructed from .028 kraft chipboard and features a peel-and-seal closure that bonds securely without tape or moisture activation. A pull-tab tear strip lets recipients open the mailer cleanly without tools or risk of damaging contents.
These mailers are a practical fit for e-commerce order fulfillment, print distribution, retail shipping, and document handling where maintaining the dimensional integrity of enclosed materials is critical. The lightweight chipboard construction helps control per-piece postage and carrier costs at high send volumes.
Each mailer measures 12-3/4" x 15" and is sold in cases of 100. The parcel-friendly format supports routine replenishment without special freight coordination, making it easy to maintain consistent stock in active shipping operations.
