Dextrin Adhesive Glue For Corrugated Cardboard
Introduction – What Is Dextrin Adhesive Glue for Corrugated Cardboard
Dextrin adhesive glue for corrugated cardboard is a water-based, starch-derived bonding material used widely in carton, packaging, paper converting and lamination applications. It offers quick tack, low cost, environmental safety and easy clean-up, making it ideal for high-speed corrugation lines.
Description & Meaning
Dextrin adhesive glue for corrugated cardboard is produced by controlled hydrolysis of starch, forming a low-viscosity, fast-setting binder. Its rheology and tack can be customized by modifying solids, pH, additives and plasticizers.
Preparation & How to Make Dextrin Adhesive Glue for Corrugated Cardboard
-
Heat water to 55–60°C.
-
Disperse dextrin powder under continuous stirring.
-
Add preservatives, plasticizers (glycerin or sorbitol), and optional tackifiers.
-
Adjust pH with mild alkali.
-
Mix until homogeneous.
-
Cool and filter before packaging.
Manufacturing Process
-
Dry blending: Dextrin powder is sieved and homogenized.
-
Wet mixing: Powder is introduced into hot water under agitation.
-
Viscosity adjustment: Borax, sodium silicate or plasticizers are added depending on application.
-
Defoming & filtration: Air removal and impurity filtration.
-
Final QC: Viscosity, solids, pH and drying time control.
