Buying Guide
How to Choose Corrugated Board Glue from China
A sourcing guide for selecting corrugated board glue based on paper grade, machine speed, viscosity, and bonding requirements.
Quick Answer
To choose corrugated board glue from China, buyers should evaluate paper type, production speed, glue viscosity, gel temperature, bond strength, storage stability, and supplier technical support. Price per ton is important, but poor bonding can cost more through waste, delamination, and customer claims.
What Corrugated Board Glue Does
Corrugated board glue bonds liner paper and corrugating medium into stable board structures. It must set quickly enough for production speed while keeping enough open time for proper bonding.
Key Specifications to Request
Viscosity range, usually measured by Stein-Hall cup or local factory method.
Gelatinization temperature and recommended operating temperature.
pH value, especially when comparing traditional and alkali-free formulations.
Shelf life for powder or liquid adhesive.
Recommended mixing ratio and preparation process.
Common Buyer Mistakes
Many buyers compare glue only by price. A better comparison includes consumption per square meter, board strength, waste rate, machine speed, and technical support.
Supplier Verification
Ask the supplier for product data sheets, sample policy, export packaging, customer applications, and troubleshooting support. For adhesive products, the supplier's ability to solve production problems is as important as the formulation itself.
PackTrades Recommendation
If your factory has high-speed corrugating equipment, ask for performance data under similar line speed and paper grade. For safer and greener production, compare alkali-free adhesive options.
