Stayflats Plus® mailers deliver rigid, lightweight protection for flat items without requiring added stiffeners. The chipboard construction resists flexing throughout transit, keeping contents flat and undamaged from packing station to final destination. The white exterior presents a clean, professional appearance suited to customer-facing shipments.
These mailers are well-suited to e-commerce fulfillment, print and photography studios, legal and medical document distribution, and retail operations shipping artwork, certificates, or promotional materials. Any application requiring reliable flat protection in a peel-and-seal format benefits from this format.
Closure is handled by a peel-and-seal adhesive strip that requires no tape or additional sealing equipment. A pull-tab tear strip on the receiving end allows clean, tool-free opening without damage to contents. Each pack contains 25 mailers and weighs approximately 7.24 lbs. Ships via parcel.
