The 15 x 12 1/2 x 1 inch White Stayflats® Gusseted Mailer is built from .020 white chipboard that resists bending and flexing without additional internal stiffeners. The 1" gusset expansion sets these apart from standard flat mailers, accommodating items with moderate thickness while maintaining the rigid, protective profile the Stayflats® line is known for.
These mailers are well-suited for photographers, print shops, catalog fulfillment operations, and e-commerce retailers shipping framed prints, multi-page booklets, folded garments, or flat-pack accessories. Any application requiring crease-free delivery of semi-thick contents benefits from the gusseted format over a non-expanding rigid mailer.
Construction is .020 white chipboard throughout, with a peel-and-seal adhesive strip for fast closure in high-volume packing environments and a pull-tab tear strip for tool-free recipient opening. Mailers are lightweight, helping control actual and dimensional weight costs across carriers. Each case contains 100 mailers.
