The GLOBAL INDUSTRIAL B68366 is a corrugated jumbo fold-over mailer designed for shipping and storing oversized flat materials such as posters, prints, and portfolios. Built from ECT-32 oyster white corrugated board, these mailers provide rigid protection comparable to 200-pound burst-test construction. Each mailer opens fully flat for straightforward loading, then closes with fold-over flaps that seal securely over the contents. The design ships and stores flat, reducing storage footprint when not in use. Sold in a pack of 20 units, the B68366 is suited for mailrooms, fulfillment operations, shipping departments, and professional service environments handling large-format documents or artwork.
These mailers are intended for oversized flat items that require protection from bending and surface damage during transit. The full fold-open design accommodates easy insertion and removal of materials without forcing or bending contents. The ECT-32 corrugated construction provides edge crush resistance appropriate for standard parcel shipping environments. Typical users include print shops, architectural and design firms, photography studios, and general fulfillment operations that regularly ship large-format materials.
Designed as a general-purpose jumbo fold-over mailer for oversized flat items including posters, prints, and portfolio materials requiring rigid corrugated protection during shipping.
No tools are required to assemble or seal these mailers. Ensure contents lie flat and centered before folding flaps to achieve a secure closure. Apply pressure-sensitive or water-activated tape across the sealed flap edge to meet carrier requirements for parcel integrity. Store unused mailers flat in a dry environment to maintain board integrity.
