Constructed from 200\/ECT-32-B kraft corrugated board, these one-piece tubes ship flat to conserve storage space and assemble without tape or glue, making them a practical choice for high-volume shipping operations. The square profile eliminates rolling during handling, staging, and transit, which reduces the risk of product movement and damage. Each pack contains 25 tubes. This product is equivalent to part number S-1578K.\u003c\/p\u003e\u003cp\u003eThese square mailing tubes are suited for warehouse, distribution, and fulfillment environments that require efficient, stackable tube mailers. The flat-pack design minimizes shelf footprint before assembly, and the no-tape, no-glue construction allows fast setup on the packing line. Typical applications include shipping posters, blueprints, drawings, and other rolled or elongated documents and materials that benefit from a tube-style mailer with stable, non-rolling geometry.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSquare profile prevents rolling during handling and transit\u003c\/li\u003e\n\u003cli\u003eShips flat to reduce storage space before assembly\u003c\/li\u003e\n\u003cli\u003eOne-piece construction folds together without tape or glue\u003c\/li\u003e\n\u003cli\u003eBuilt from 200\/ECT-32-B kraft corrugated board for structural integrity\u003c\/li\u003e\n\u003cli\u003eEquivalent to part number S-1578K\u003c\/li\u003e\n\u003cli\u003eSold in packs of 25\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct equivalent to part number S-1578K.
