Bsc Preferred M5518 Square Corrugated Mailing Tubes 25-pack

Product Description

The BSC PREFERRED M5518 is a pack of 25 flat-shipping, one-piece square corrugated mailing tubes designed for packing and shipping applications. Unlike traditional round mailing tubes, the square profile prevents rolling during handling and storage, making them more stable on conveyor systems and easier to bundle together. Each tube is constructed from 200/ECT-32-B white corrugated material, providing reliable crush resistance for standard parcel shipping. The tubes ship flat to reduce storage footprint and fold into shape quickly without tape or glue, cutting prep time on the packing line. This item is sold as a pack of 25 units.

These square mailing tubes are suited for mailrooms, fulfillment centers, distribution operations, and light industrial shipping departments. The flat-pack format makes them practical for locations with limited storage space. Because they fold together without adhesive, no additional materials are needed at the point of pack. Typical applications include shipping documents, posters, blueprints, and similarly sized rolled or flat items that require a rigid outer shell for transit protection. This product is equivalent to part number S-11345.
