Spiral-Wound Paper Core Tubes
Engineered with high-tensile multi-ply kraft paper and high-tack moisture-resistant bonding, our spiral paper core tubes sustain extreme winding tension, radial load, and continuous rotary speed.
High-Load Performance & Structural Integrity
High-strength spiral-wound cylindrical paper tubes engineered with specialized high-tensile virgin and recycled kraft plies and water-resistant adhesives. Built to sustain immense winding tension, external radial pressure, and high-speed rotary processing across paper mills, plastic film extruders, aluminum foils, adhesive tape converters, and industrial textile winders.
Key Structural Advantages:
- Multi-ply spiral lamination delivering uniform structural burst strength and high hoop stress resistance
- Burr-free automated slitter cut ends for flush reel alignment on high-speed industrial rewinders
- Custom wall thickness up to 20 mm calibrated for extreme winding tension and heavy outer roll weight
- High torsional rigidity preventing slipping or de-lamination on mechanical drive mandrels
- 100% recyclable premium Kraft paper composition supporting circular packaging mandates

Plastic Film Extrusion
High-tensile cores designed to resist inward compressive tension exerted by tightly wound elastic plastic films.
Metallic Foil Spooling
Heavy caliber core tubes supporting non-ferrous metal coil winding with zero core depression.
Industrial Fabric Beams
Wide-width core tubes up to 5,000 mm for heavy carpet backings, non-woven geotextiles, and fiber webs.
Zero-Defect Manufacturing Lifecycle
From calibrated raw material screening to final hydraulic crush testing, every production phase operates under ISO 9001:2015 control.
High-Tensile Kraft Slitting
Parent kraft rolls are slitted into calibrated ribbon plies and conditioned for controlled moisture equilibrium.
Cascading Adhesive Application
Each ply passes through multi-tier glue baths applying high-tack water-soluble polymer adhesives.
Continuous Mandrel Spiral Winding
High-torque winding belts continuously wrap plies around precision-ground steel mandrels under controlled tension.
In-Line Flying Knife Slitting
Synchronized servo-driven circular knives cut tubes on the fly to exact blueprint lengths with burr-free edges.
Frequently Asked Questions
Key technical answers for procurement heads, packaging engineers, and supply chain managers.
What internal diameters (ID) are available for your spiral paper tubes?
We manufacture core tubes from 25mm (1 inch) up to 305mm (12 inches) ID, with standard 76mm (3-inch) and 152mm (6-inch) sizes readily available.
How do you prevent paper cores from collapsing under high winding tension?
By calibrating kraft ply grammage, spiral angle, and polymer glue solid content, we engineer wall thicknesses up to 20mm capable of sustaining radial crush ratings over 35 kN/m.
Are custom lengths and outer liner branding available?
Yes. Tubes can be precision cut from 100mm up to 6000mm, with options for custom colored outer liners or corporate logo printing.
