The BSC PREFERRED MRX2L corrugated mailer is a self-sealing shipping solution built for small, lightweight fragile items. Constructed from 200/ECT-32-B white corrugated board, these mailers fold to create double walls of protection on the front and sides without requiring tape, glue, or staples. The result is a secure enclosure that resists crushing during transit while keeping package weight low. Each pack contains 50 mailers, making them a practical stock item for mailrooms, shipping departments, and fulfillment operations handling regular outbound parcels.
These mailers are suited for residential and commercial shipping applications where protecting lightweight fragile goods is the priority. Typical use cases include e-commerce fulfillment, parts distribution, and retail returns. The self-closing design speeds up the packing process and eliminates the need for additional sealing supplies at the workstation. The white corrugated surface also accepts standard shipping labels cleanly.
Designed as a general-purpose corrugated mailer suitable for shipping small, lightweight fragile items across standard parcel and postal carrier services.
No tools or fasteners are required to assemble these mailers. Fold along the pre-scored lines and tuck the closure flap to seal. Ensure contents are properly cushioned before sealing to prevent movement inside the mailer during transit. Store unused mailers flat in a dry environment to maintain board integrity.
