A paper core features cylindrical layers of rolled paper that are compressed and molded to create sturdy products. These cores can withstand pressure for heavy-duty industrial uses. A paper tube may have less internal reinforcement than paper cores, which makes them more suitable for lightweight applications. Here are some factors that differentiate an industrial paper tube from a paper core:
Manufacturing Techniques
A paper tube producer wraps paper strips around a central mandrel at an angle. Wrapping paper strips at an angle along the length of the tube instead of around its circumference enhances flexibility. Paper cores undergo convolute winding, wrapping paper layers around mandrels to form cylinders. The vertical wrap gives paper cores enhanced strength and durability. This structural integrity makes convolute-wound cores suited for industrial winding needs. The simpler manufacturing of spiral-wound tubes makes them suitable for lighter applications.
Material Composition
The material types used in cores and tubes differentiate the products for specific uses. Thicker, denser paper fibers offer structural reinforcement for industrial tubing. The heavy recycled paper provides strength and durability under tension. Polymeric resins applied after forming add water resistance and further reinforce paper cores. Thinner, lower-cost paper content suits lightweight paper tubes. Paper tubes may undergo less post-forming treatment and have different industrial durability than reinforced cores.
Industrial Applications
Materials such as textiles, adhesives, laminates, and foil require solid cores for storage to confirm they remain securely wound and protected during handling and transport. Industrial paper tube cores withstand the materials’ weight, pressure, and winding forces. Large tubes can transport goods like carpets and piping. These applications highlight the inner strength of reinforced cores designed to meet the demands of industrial use. Convolute-wound cores have the strength to withstand manufacturing pressures. Spiral-wound tubes offer flexible packaging suited for lighter handling.
Strength and Durability
Reinforced paper cores can support large reels of high-gauge steel strips weighing several tons. This demonstrates their superior strength compared to lighter paper tubes. Wrapped around a sturdy paper core, the steel’s weight transfers to the core. Convolute winding and resin reinforcement provide the core with strength to support heavy industrial materials. Lighter-gauge paper tubes might collapse under such loads. Thicker paper construction and polymeric resins give industrial tubes the strength, moisture resistance, and durability needed for demanding winding applications.
Customization and Design
A manufacturer can fulfill custom orders specifying the tube’s inner diameter, outer diameter, wall thickness, and tube length. They can also create custom colors, prints, and finishes. This customization results in a spiral-wound tube that matches the customer’s packaging needs. While paper cores offer size customization, tubes allow multiple surface customization options for product promotion. Adding labels and decorative graphics to a tube results in branded packaging solutions tailored to specific customer needs.
