Cardboard Tubes

Cardboard Tubes

Cardboard tubes are cylindrical paper products which vary in size and thickness and can have greater strength than cardboard or plastic boxes. Many industries have found cardboard tubes to be a cost-effective solution for storing, shipping, mailing, manufacturing and distributing. Automotive, electronics and food industries use cardboard tubes for storage, shipping, parts protection, insulation and distribution. Other common industrial uses for paper tubes include fireworks canisters and rocket bodies; poster print containers; point of purchase displays for consumer items; coin banks for non-profit fundraising, and paper cores for winding electrical, fabric, adhesive, paper and converting products. Contractors and construction industries use large, highly durable cardboard tubes called sonotubes for concrete pillar forming.
 
Many different kinds of paper tubes are manufactured for very different uses. Paper tubes are made from wood pulp bases including fiberboard, paperboard, kraft paper and paper-adhesive composites; many of these harder paper-based materials are generically considered cardboard. The wood pulp materials are spiral-wound for tensile strength and often contain multiple layers mixed with adhesives for structural strength. Thickness of tube walls, length and diameter are all variable, and paper tubes are sometimes coated or lined in wax for temperature and moisture resistance, metal foil for moisture protection or decoration, or kraft paper for decoration, printing and labeling. Most food-grade paper tubes are foil-lined, and paper tubes made for military applications are often wax-coated for heat resistance. Electrical-grade paper tubes are moisture resistant and are used as insulators for connector wires.

Tubes are sometimes lined with materials such as metal sheeting, plastic, rubber and glass. Sonotubes are often lined with a thin layer of plastic, and medical and biochemical items are usually shipped in metal-lined tubes. Coin banks, fireworks cases, point of purchase displays and some mailing tubes are coated in foil or kraft paper and screen printed with product information. Cardboard tubes which are used as containers are closed on one or both ends by tin caps, wooden caps, plastic plugs, crimped ends, snap-folding ends, screw tops or telescopic-type closures.

Cardboard tubes are manufactured from recycled paper and can be recycled over again, making them a cost-efficient alternative to metal, plastic, glass and wood. Not only are paper tubes cost-effective, but they also rival plastic and metal tubes in strength-to-weight ratio, making them a perfect solution for mailing, shipping, storing and distributing almost any material. Cardboard is a porous material, making it possible for electrical insulation tubes to absorb damaging moisture, preventing shorts, while paper mailing tubes help keep valuable posters and prints dry and paper food canisters keep spices and powders from clumping with moisture. Tough, flexible, and renewable, cardboard tubes are a great commercial and industrial solution.
