Bsc Preferred M3644 Corrugated Mailers 200/ECT-32-B 50 Pack

Product Description

The BSC PREFERRED M3644 is a corrugated mailer designed for shipping small, lightweight fragile items without the need for tape, glue, or staples. Constructed from 200/ECT-32-B white corrugated board, each mailer folds to create double walls of protection on the front and sides. This self-sealing, crush-resistant design reduces packaging time and keeps contents secure in transit. The lightweight construction helps keep postage costs low. Each pack contains 50 mailers and is suited for mailrooms, warehouses, e-commerce fulfillment centers, and any operation that ships small fragile goods on a regular basis.

The M3644 mailer is well suited for light-duty shipping applications where standard corrugated boxes are too bulky or heavy. The fold-and-lock closure system eliminates the need for additional sealing supplies, making it practical for high-volume packing workflows. Typical use cases include shipping small parts, samples, documents, electronics accessories, and other fragile items that require more protection than a padded envelope but do not justify a full corrugated box. Each pack contains 50 units, sold by the pack.

Handle packed mailers with care to avoid puncture or crushing prior to shipment.
