A paper core is a cylindrical structure made using paper or paperboard. Paper tube manufacturers offer different sizes and strengths depending on the intended application. The tubes feature multiple layers laminated or bonded together using a strong adhesive. While simple in design, paper tubes are strong, reliable, and versatile. Here are the top uses of paper tubes:
1. Packaging & Containing
Paper cores and tubes are popular in the packaging industry. The cylindrical tubes offer structure and strength and come in different designs. You can find paper cores for packaging films, metal foils and strappings, tape labels, mailing, clothing, and floor coverings. Yarn carriers, paper mill cores, converter cores, spools, and reels also feature paper tubes.
Manufacturing and packaging companies prefer paper tubes for their many benefits, including strength and unique brand packaging. Paper tubes are lightweight, flexible, and cheaper to make and transport than traditional packages. The material is also recyclable, making paper tubes an eco-friendly choice. You can order lightweight or heavy-duty options and customize the size and other parameters.
Paper tubes also come in custom colors and additional elements like labels, brand images, and stylish intricate details. Here are some unique ways different industries and companies use paper tubes:
- Textile industry tubes can be used as yarn carriers and clothing packaging
- Food-grade paper tubes carry cereals, dry ingredients, fast foods, and beverages
- Paper tubes are perfect for storing and transporting rollable materials like posters, maps, newspapers, and paintings
- Winding and dispensing labels, adhesive tapes, paper, tissue, paper towels, and plastic films work well in round packaging
- Convoluted paper tubes can wind large rolls in plastic film production plants and paper mills
- They can be used to reinforce corners and space products in packaging boxes to prevent movement during transit
2. Construction & Forming
Paper tubes come in sturdy, heavy-walled designs with various applications in the construction industry. The cores can wind sheets of flexible materials into rolls for easy storing, transporting, and dispensing.
Heavy-duty tubes have architectural applications. Paperboard sonotubes provide the framework for concrete columns, pillars, stub piers, and light poles in building and construction. Spiral wound paperboard tubes are also used to dispense caulk.
The construction industry uses paper tubes in various other ways. Large-diameter spiral wound tubes form casts for concrete pillars. Paper dowel sleeves can help create plumbing and electric wiring openings/channels within the cast concrete. Architects may also use paper tubes as temporary shelter framing. Construction paper tubes feature weather-resistant internal and external plies. They’re also a lightweight, affordable, high-strength substitute for metal tubes.
3. Insulating, Damping & Masking
Paper tubes are inherently fibrous and can help to dampen vibration when shipping fragile items. You can use them to protect glass, boards, sheets, and other materials from abrasion during transportation.
Paper tubes also have better thermal insulating properties than metal tubing. You can use them to help regulate internal temperatures when shipping heat-sensitive goods. Items within paper tube packaging are also safe from drastic temperature shifts.
Manufacturers can produce paper tubes engineered with filled resins. The resins provide thermal conductivity, so the paper tubes can be used for insulation and conductivity. Paper tubes protect and preserve spindles, polished shafts, plug gages, end mill teeth, and bolt threads. The tubes protect these delicate parts from contact with other metal components. Paper tubes also mask shafts and threads for selective application of polish, coatings, and adhesives.
Paper tubes have various other applications, including spacing and supporting where the tubes act as display poles. You can use them to support signs in exhibits and stores. Paper tubes are also spacers that protect automotive wheel hubs from damage and movement. The tubes can wind different materials for easy carrying. Paper spools can roll up sod in the agricultural industry and are often the preferred choice for dispensing wires, tubing, cables, foils, ropes, and yarns.
Some paper tubes are used as elements in machines. Other uses include pyrotechnic tubes for fireworks and explosive bolts. You can also find paper tube straws for sipping beverages.
Paper tube applications are limitless and keep evolving. Homeowners also keep finding new ways to reuse packaging paper tubes. They can provide support and shielding for young plants, serve as storage containers for dry goods, and be used in various DIY projects.
