Meaning of Dextrin Adhesive
Dextrin adhesive is a starch-derived, water-soluble bonding material widely used for paper, cardboard, labeling and general packaging applications. It offers fast tack, clean application, good film formation and cost-effective performance.
Definition of Dextrin Glue
Dextrin glue is defined as an adhesive produced by controlled hydrolysis of starch, resulting in shorter-chain polymers that dissolve easily in water and create a smooth, stable adhesive paste.
It is considered a natural carbohydrate-based adhesive, making it safe, biodegradable and suitable for food-related or eco-focused industries.
Raw Materials & Ingredients of Dextrin Adhesive
Typical materials used in dextrin adhesive manufacturing include:
-
White or Yellow Dextrin – primary binder; provides viscosity and adhesion
-
Water – solvent for hydration and paste formation
-
Plasticizers (e.g., glycerin, sorbitol) – improve flexibility and tack
-
Preservatives – prevent microbial growth
-
Buffers / pH Regulators (e.g., borax) – enhance adhesion and stability
-
Fillers (optional: clay, calcium carbonate) – modify body and application properties
-
Optional Additives
-
Foam suppressants
-
Wetting agents
-
Viscosity modifiers
-
Antislip agents (depending on application)
-

Summary
Dextrin adhesive is a natural, starch-derived glue used extensively in paper and packaging industries due to its low cost, safety profile, biodegradability and good bonding performance on porous materials. Its formulation is based on dextrin, water and a range of optional additives for viscosity, stability and tack control.
