FAQ
What Is Alkali-Free Adhesive?
A direct explanation of alkali-free adhesive, how it differs from traditional starch glue, and where it is used.
Quick Answer
Alkali-free adhesive is a packaging adhesive formulation that does not use caustic soda. It is commonly used in corrugated board and paper packaging production to reduce corrosion, improve worker safety, simplify preparation, and support cleaner production.
Why Traditional Adhesives Use Alkali
Traditional starch adhesives often use caustic soda to adjust gelatinization behavior and viscosity. This works, but it can increase corrosion risk, handling safety concerns, and process complexity.
Benefits of Alkali-Free Adhesive
No caustic soda in the formulation.
Reduced equipment corrosion and maintenance pressure.
Safer handling for operators.
More environmentally friendly production process.
Stable bonding performance for corrugated board applications.
Typical Applications
Alkali-free adhesive can be used for laminating, core bonding, facing, and other corrugated board production steps depending on the formulation.
