Jelly Gelatin Glue Knowledge
What Is Jelly Glue?
Jelly glue, also known as animal glue or protein glue, is a natural, water-based adhesive made from collagen protein extracted from animal bones or hides. It is delivered in a jelly-like solid form and is reactivated by heating. Jelly glue is prized for its strong bonding power, fast setting time, and eco-friendliness.
Key Features of Jelly Glue
√ Reversible when heated
√ Fast drying and quick tack
√ Low odor during application
√ Biodegradable and non-toxic
√ Strong adhesion to porous surfaces
Ideal for industries seeking eco-friendly, cost-effective, and high-performance glue solutions.
Main Applications of Jelly Glue
√ Rigid box manufacturing (gift boxes, jewelry boxes)
√ Bookbinding (spine glue, case-in glue)
√ Paper tube and core winding
√ Labeling for glass bottles (wine, spirits)
√ Laminating decorative paper on chipboard
√ Packaging and carton edge sealing
Why Use Jelly Glue in Packaging?
Jelly glue offers excellent bonding for luxury packaging materials like coated paper, greyboard, and specialty films. It supports automated gluing machines and enables clean, smooth finishes—perfect for premium brands focused on appearance and sustainability.
How to Use Jelly Glue
Heat the jelly glue to 60–75°C until it becomes liquid
Apply evenly using a roller, nozzle, or brush
Bond materials while glue is still hot
Hold pressure briefly for fast setting
Compatible with most automated box making and labeling machines.
Jelly Glue vs Hot Melt & White Glue
| Feature | Jelly Glue | Hot Melt Glue | White Glue (PVA) |
|---|---|---|---|
| Base | Natural protein | Synthetic resin | Synthetic polymer |
| Eco-friendly | ✅ Yes | ❌ No | ⚠️ Partially |
| Heat reversible | ✅ Yes | ❌ No | ❌ No |
| Drying time | Fast | Very fast | Slower |
| Surface match | Paper/board | Plastic/cardboard | Paper/cardboard |
Tips for Optimal Use
Keep glue temperature between 65–70°C
Avoid overheating (above 80°C may degrade protein)
Clean equipment with warm water after use
Use anti-mold additives for long-term storage
Store in dry, cool environments
