  • ColorKraft

  • Crimped ends seal contents without extra tape
  • Kraft construction resists crushing during transit

Shipping Tubes for Documents

Partners Brand S4030K mailing tubes come in a pack of 15 and measure 4 inches by 30 inches. The crimped ends hold blueprints, posters or rolled artwork without extra caps. Kraft construction resists tears during transit. These tubes ship new and ready for immediate use in mailroom or office settings.

Capacity and Headroom

Each tube accepts items up to 30 inches long and roughly 4 inches in diameter. A 15-count pack covers routine mailing batches and small project runs. Very large posters or high-volume daily shipping will exhaust the supply quickly. The fixed length means oversized documents need a different solution.

Crimped End Closure

The crimped ends seal without tape or plastic caps, saving packing time. They stay closed under normal handling but are not designed for heavy stacking or rough freight. Buyers who need reusable, adjustable or lockable closures should consider other packaging styles.

Questions about this item

Will these 4" x 30" tubes fit alongside the 3" tubes I already use in the same mailing box?

The 4-inch diameter is wider than 3-inch tubes, so they need a box with at least 4 inches of internal width; measure your existing box before combining them.

How can I confirm the crimped ends on the S4030K tubes are sealed well enough for shipping?

Press each end firmly — properly crimped ends stay flat and resist reopening; if an end pops open, fold and tape it before mailing.

Does the 15-pack include end caps or do I need to buy caps separately?

The tubes have crimped ends built in, so no separate caps are included or required for basic closure.
