Challenge
Paper tube and core manufacturers face persistent issues with conventional starch-based adhesives: sedimentation during storage or application, inconsistent mixing with water leading to lumps or phase separation, and inadequate wet/dry bonding strength that causes delamination under high-speed winding or humid conditions. These problems reduce production efficiency, increase waste, and compromise the structural integrity of multilayer paper tubes used in packaging, textiles, and industrial applications.
Solution
Stardex® 2155-Tube, a high-strength modified starch adhesive powder developed by Premier Starch, addresses these limitations through advanced starch modification technology. Formulated for normal water solubility and optimized viscosity (60–120 seconds, B4 cup or 40-60 seconds B6 cup), it delivers a stable, ready-to-use adhesive system specifically engineered for high-speed tube-winding machines.
Key differentiators include:
- No settling problem: The modified starch matrix maintains uniform suspension even after prolonged storage or during continuous operation, eliminating sedimentation that plagues standard dextrins.
- Excellent powder–water mixing: The product disperses rapidly and homogeneously in hot water with minimal agitation, forming a lump-free, stable paste without any settling, ensuring consistent glue-line application.
- Superior bonding strength: It provides exceptional dry and wet adhesion, forming a smooth, uniform film that ensures multilayer paper structures remain firmly bonded under mechanical stress and moisture exposure.
Additional technical advantages include fast drying, dimensional stability, and full compatibility with high-speed winding equipment, while remaining biodegradable and safe for industrial use.
Results & Impact
Manufacturers adopting Stardex® 2155-Tube report zero settling-related downtime, improved machine runnability, and significantly higher bond integrity—even in demanding multilayer cores. Production speeds increase without quality compromise, waste is minimized, and end-product performance (burst strength and moisture resistance) exceeds industry benchmarks.
