The BSC PREFERRED M38261 is a one-piece jumbo fold over mailer designed for shipping and protecting oversized flat items. Built from 200/ECT-32-B white corrugated board, this mailer delivers structural rigidity and a clean presentation suitable for professional and commercial shipping applications. The single-piece construction opens completely flat for fast, efficient loading. Place the item on the open mailer, fold over the top flap, and secure with tape. Each pack contains 20 mailers. The corrugated construction resists crushing during transit, making it a reliable choice for fragile or high-value flat goods.
This mailer is intended for shipping portfolios, architectural drawings, blueprints, large maps, posters, and similar oversized flat documents or materials. It is well suited for print shops, architectural firms, engineering offices, and distribution centers that regularly ship large-format flat items. The fold-over design eliminates the need for separate box assembly and reduces pack time on the shipping floor. Each pack ships as a single unit of measure.
Designed as a direct equivalent to part number S-5597. Suitable for general-purpose flat-item mailer applications requiring a jumbo one-piece corrugated format.
No tools required for assembly. Open the mailer completely flat before loading to avoid creasing the contents. Seal all open edges with pressure-sensitive packing tape rated for corrugated cartons. Store flat in a dry environment prior to use to maintain board integrity.
