Poster Tubes
Poster tubes are a type of mailing or shipping tube that are used to safely transport roll-able, unframed art that cannot be folded. They may also carry items like blueprints, large papers, signs, banners and important documents that must remain increased. They provide adequate protection against denting, dropping, crushing and bending that may occur because of rough handling during transit.

Design of Poster Tubes
These tubes are made from wood pulp fibers and are cylindrical in shape. The cardboard material is composed of several layers that are cut into ribbons, coated with adhesive or fibers for reinforcement and wrapped around a mandrel in the desired shape of the tube at a continuous angle. The long paper tube is then cut to size. Poster tubes protect fragile paper products better than cardboard boxes not only because of their round shape, but they also have dense, thick walls that provide more strength. It’s important to choose the right size of tube. A large tube may damage the product because it might slide back and forth. If it is too small, there may not be enough room for the poster and a cap or folded end. Optimally, the tube should be slightly longer than the rolled item. The ends are plugged by caps that are snapped on or glued and made of plastic, metal or wood. The ends might also be crimped and glued together. Some poster tube exteriors are covered in kraft paper to provide a nice finish, colors, text designs or images. Some more expensive poster tubes are waterproof and covered in a polyester canvas. They often have zippers, shoulder straps and compartments. These are not used for mailing, but rather personal transport.
Specifications of Poster Tubes
Poster tubes are inexpensive and easily purchased at any post office, shipping store or office supply store. They may also be bought in bulk from an online cardboard tube manufacturer by businesses that ship large amounts of valuable paper products like architecture firms and poster stores. Poster tubes are available in many different sizes to accommodate the large range of items with different lengths and widths, although most are not longer than 48 inches to comply with shipping standards. Some are telescoping, meaning they are adjustable and may retract or expand. All tubes made of cardboard, no matter what their purpose, may be used multiple times. When they are worn and must be disposed of, they are easily recycled. When shipping internationally, use a tube that is specifically made for heavy-duty applications.
