Bsc Preferred MLR7 Corrugated Mailers 200/ECT-32-B 50 Pack

Product Description

The BSC PREFERRED MLR7 is a self-sealing corrugated mailer designed to protect small, lightweight fragile items during shipping without the need for tape, glue, or staples. Manufactured from 200/ECT-32-B white corrugated board, each mailer folds to create double walls of protection on the front and sides, providing crush resistance suited to parcels moving through standard carrier handling. The lightweight construction keeps dimensional weight low, reducing postage costs. Each pack contains 50 mailers. These are a practical choice for fulfillment operations, e-commerce sellers, and distribution centers shipping breakable or delicate goods in volume.

The MLR7 mailer is used in light industrial, commercial, and office shipping applications where small fragile items require reliable protection without additional packing materials. The self-locking fold design eliminates the need for a separate sealing step, making it efficient for high-volume packing lines. Typical use cases include shipping small parts, samples, retail products, and similar items where a compact, rigid mailer is preferred over a padded envelope or poly bag. Sold as a pack of 50 units.

Installation Notes

No tools are required to assemble or seal the MLR7 mailer. Fold along the pre-scored lines and press the locking tabs into place before inserting the item. Ensure the item fits within the interior dimensions without forcing the walls apart, which could compromise the double-wall protection. Store unused mailers flat in a dry environment to maintain board integrity.
