Corrugated Mailing Tubes & Plastic End Caps

1. Measure Rolled Size Measure the length and finished diameter or cross-section of the rolled product rather than the flat sheet size alone.

2. Choose the Profile Compare round, square, and triangle shapes based on handling, storage, and conveyor considerations.

3. Select Length Strategy Use fixed-length tubes for repeatable products or telescoping/adjustable formats when product lengths vary.

4. Match the Closure Use compatible end caps or crimped-end construction as specified by the individual tube.

Large-format documents and rolled products need a package that protects their shape without requiring a fold. Mailing tubes create a long, narrow outer package that can be sized around the rolled diameter and finished length of the contents.

Round tubes are the familiar cylindrical option, but they are not the only choice. Square and triangle corrugated tubes provide flat-sided alternatives, while telescoping and adjustable formats are useful when one fixed length does not fit every product. Choose the tube and closure as a system. Verify usable dimensions, wall or board construction, cap compatibility, and how the package will be handled. Very fragile, high-value, heavy, or unusually shaped products may require additional interior protection or a different outer package. A tube lets compatible documents and prints remain rolled rather than being folded into a flat package. Round, square, and triangle formats support different handling and storage preferences. Telescoping and adjustable tubes help accommodate product families with varying lengths. Plastic end caps and crimped-end formats provide different ways to secure compatible tube styles.
