The BSC PREFERRED M302214 is a one-piece jumbo fold-over mailer designed for shipping oversized flat items such as portfolios, maps, and large-format documents. Built from 200/ECT-32-B white corrugated board, this mailer provides rigid protection during transit while maintaining a clean, professional exterior. The single-piece construction eliminates the need for pre-assembly. The mailer opens completely flat for straightforward loading, then folds over and seals with tape. Each pack contains 20 mailers. This product is used by shipping departments, print shops, and trade professionals who regularly send large flat materials.
This mailer is suited for internal shipping operations, fulfillment centers, and any application that requires a ready-to-use solution for oversized flat stock. The full open-flat design speeds up packing workflows when processing multiple shipments. The white corrugated exterior presents well for both internal transfers and outbound customer shipments.
Designed as a general-purpose fold-over mailer for oversized flat items including portfolios, maps, blueprints, and similar large flat documents requiring rigid corrugated protection.
No tools required for use. Place the item flat on the open mailer surface, fold the top panel over the contents, and secure all edges with packing tape. Store unused mailers flat in a dry environment to prevent warping of the corrugated board.
