Rewettable adhesive (also known as saliva-activated adhesive) is a water-soluble adhesive that forms a transparent film after being coated on the paper surface and dried. It reactivates its adhesive properties when moistened with water. Main Components and Types
The core component of rewettable adhesive is mostly water-soluble polymer materials.

Additives: Ethylene glycol and glycerol act as wetting agents to accelerate dissolution. Some formulations include cross-linking agents to enhance stability (such as dextrin-acrylamide graft copolymer).
