Bsc Preferred MRX3L Corrugated Mailers White Pack of 50

Product Description

The BSC PREFERRED MRX3L is a self-sealing corrugated mailer designed to protect small, lightweight fragile items during shipping without requiring tape, glue, or staples. Constructed from 200/ECT-32-B white corrugated material, these mailers fold to create double walls of protection on the front and sides, giving contents crush-resistant enclosure. The lightweight construction helps keep package weight low, which is a practical consideration for volume shippers looking to manage postage costs. Each pack contains 50 mailers, making them well-suited for shipping departments, fulfillment operations, and supply rooms that process regular outbound parcels.

These corrugated mailers are appropriate for residential, commercial, and industrial shipping applications where small, fragile items need reliable transit protection. The self-sealing design eliminates the need for additional sealing materials, streamlining pack-out workflows. Typical use cases include sending hardware samples, small components, documents, or other lightweight goods that require more protection than a padded envelope but do not require a full corrugated box. Sold in packs of 50, the MRX3L is suitable for both low-volume and moderate-volume shipping operations.

Installation Notes

No tools or fasteners are required to seal these mailers. Fold the mailer along the pre-scored lines and close using the built-in self-sealing mechanism.

Store unused mailers flat in a dry location to preserve corrugated material integrity.
