White Stayflats® Mailers in the 6x6" size are self-stiffening chipboard mailers that protect flat contents from bending and creasing without requiring separate stiffening inserts. The white chipboard construction provides built-in rigidity, and the tab lock closure secures the mailer without tape or adhesive.
These mailers are well suited for photos, greeting cards, documents, promotional materials, fabric swatches, and similar flat or semi-rigid items. Fulfillment centers, print shops, photo labs, and retail distributors rely on them for both direct-to-consumer shipments and B2B distribution where presentation and protection matter equally.
Constructed from white chipboard, the mailer's lightweight build helps manage postage costs at scale. Each case contains 200 mailers and ships via parcel carrier, making inventory replenishment efficient for high-volume packing operations.
