Fiber tubes are very similar in structure to telescope tubes. Fiber Tubes are made up of paper canisters that utilize friction fit plastic plugs, metal end closures or paper caps. Fiber tubes are usually used for higher end packaging like candles, retail packaging, and bath and skin care product packaging or in some cases, for packaging promotional kits. Fiber tubes are not usually used for food packaging because of the materials used to produce them. The paper material used for fiber tubes is mostly recycled paper as this is a more cost-effective and more environmentally friendly way to package certain products. The width of the insides of fiber tubes usually range from ¼ inches to 5 inches wide, wall thickness from 0.40 to 0.120, and length up to 24 inches, and sometimes come with grade foil or grease proof liners.
These tubes can come in either two piece or three piece designs. In the two-piece design, the outer tube (usually a little wider in diameter) serves as the cap and the inner tube (usually smaller in diameter than the outer tube) serves as the container holding the items. There are also a few options with regards to the sealing of this item. The first is to seal the ends with seamed on metal, or utilize curl and disc paper ends as closures. The three piece tubes come with dual wall construction with both the inner and outer tubes having the same diameter. The ends of these tubes can also be closed off using seamed on metal ends or curl and disc paper ends.
Fiber tubes vary because they are not usually spiral wound like other paper tubes. These cans however are very lightweight and more durable than regular paper tubes. Customers who require specific designs on their fiber tubes will have to notify the manufacturer so the designs can be imprinted on the tube itself. Because it is not spirally wound, the label or design for the specific customer cannot be added after the fiber tube has ben produced. Fiber tubes cannot be used for large scale or industrial scale purposes because they are not strong enough to handle heavy materials.
