White Stayflats® Mailers in the 7 x 9 inch size are constructed from rigid white chipboard that maintains a flat panel without any added stiffeners. The self-contained construction reduces packing station prep time and eliminates the cost of separate rigids, making these mailers efficient for operations that prioritize speed and material economy.

The tab lock closure secures contents without tape, producing a clean, professional presentation on arrival. The white exterior suits retail e-commerce shipments, photography studios, print shops, and direct mail campaigns where appearance at the point of delivery matters. These mailers also work well in card and stationery fulfillment environments where consistent flat protection is required at volume.

Each mailer is sold in cases of 100. The parcel-friendly format integrates easily into standard fulfillment workflows and ships via parcel carrier without special handling requirements.
