The BSC PREFERRED ML1283K is a kraft corrugated literature mailer designed for shipping and storing flat documents, catalogs, and printed materials. Constructed from 200/ECT-32-B corrugated board, these mailers offer reliable crush resistance for standard document transit applications. The self-locking design assembles in seconds with no tape, glue, or staples required, making them efficient for high-volume mailing operations. Each pack contains 50 mailers. This SKU is equivalent to part number S-16652. Facilities managers, shipping departments, and print distributors are the primary users.
These literature mailers are suited for lightweight, flat-content shipments in residential, commercial, and light industrial settings. The ECT-32-B construction meets standard requirements for single-wall corrugated mailers used in document distribution. They are well-matched to environments where consistent, quick-assemble packaging is needed at the workstation level without additional sealing materials or tools.
Designed as a standard literature mailer suitable for flat-document and print-media shipments requiring single-wall corrugated protection.
No tools are required for assembly. Fold along pre-scored lines to form the mailer box before inserting contents. Keep cartons stored flat in a dry environment to preserve board integrity prior to use. Do not overfill beyond the rated flat-document capacity, as excess loading may compromise the self-locking closure.
