Stayflats® Do Not Bend Mailers deliver rigid, flat protection for documents, photos, certificates, and artwork that must arrive without folds or creases. Built from 100% recycled paperboard, these mailers are structurally stiff throughout transit and fully recyclable after use — combining protective performance with sustainable materials.
The pre-printed "Do Not Bend" exterior messaging communicates handling instructions directly to postal workers and carrier staff, reducing the risk of mishandling before the package reaches its destination. A top-loading, pressure-sensitive self-seal closure secures contents without additional tape or equipment, supporting efficient fulfillment in e-commerce, direct mail, photography studios, legal and medical offices, and professional document distribution.
Each mailer features an integrated tear strip for clean, tool-free recipient opening. Exterior dimensions are 9 x 11 1/2 inches, accommodating standard letter-size and slightly oversized flat contents. Sold in cases of 100 and ships via parcel.
