Keep Your Items Safe with Square Mailing Tubes
When it comes to shipping items that need to stay rolled and intact without bending or folding, square mailing tubes are an excellent option. These sturdy containers are perfect for sending documents, posters or artwork safely through the mail. The unique square shape provides additional protection, ensuring corners and edges are not damaged during transport. This design also prevents the tubes from rolling off conveyors or tables, minimizing the risk of mishandling. With square mailing tubes, you can trust that your items will arrive at their destination just as you sent them—a need that typical mailing envelopes or round tubes might not meet as well.
Varieties of Square Postal Tubes to Fit Your Needs
Square postal tubes come in various sizes and thicknesses to cater to diverse needs, ranging from compact 6-12" tubes to extra large 36-48" tubes. They also come in diameters 3" and 5" to simultaneously account for thicker or multiple documents. Whether you're a business owner shipping marketing materials or a student sending off a project, there's a tube size that's just right for you. Square mailing tubes can be made from various materials, including heavy-duty cardboard or plastic, offering different levels of protection. Some feature locking tabs for secure sealing without tape, while others come with removable caps. With these different options, square postal tubes provide a reliable and adaptable choice for all your mailing requirements.
