It's a common office mailroom conundrum - how do you safely store and deliver delicate, oversize documents without damaging the items in question with tears, creases, smudges and other unsightly marks? For standard-size paperwork and books, the answer is a literature mailer. For most other packages, the solution lies within a vast assortment of corrugated mailers. But when dealing with blueprints, posters, contracts, architectural drawings and plans, large photos and other documents that need to be gently rolled, the best option is a mailing tube.
Get out the measuring tape or ruler, because when it comes to mailing tubes and cardboard tubes, 2 things are of primary importance - the tube's diameter and the tube's length. If you select a mailing tube that's too small, you'll be forced to cram your documents into the tube, risking damage along the way.
Many mailing tubes are constructed from cardboard or fiberboard with a 3-ply, spiral-wound design that adds additional strength to the overall construction. Choose a moisture-resistant mailing tube to guard against rain drops or damage in moisture-rich environments and storage areas.
Not all cardboard tubes are created equal. Mailing tubes generally come in a round shape, but there are also square and triangular options available. Conventional round tubes usually feature removable caps that snap into place on both ends of the tube to prevent items from falling out. Some round tubes use crimped ends as a means of closure, but crimped ends offer a less-secure seal than end caps. The advantage of choosing a square or triangular mailing tube is that they won't roll on conveyor belts and are less likely to move on a mailroom cart.
