In short
Side-by-side comparison to decide the right adhesive type for your line.
Key takeaways
- Cleaner edge and lower stringing
- Different set/open time windows
- Cost vs performance trade-offs
Performance Comparison
| Factor | Jelly Adhesive (SAHO) | EVA Hot Melt (Typical) |
|---|---|---|
| Open Time | 12-30s (configurable) | 8-20s (typical) |
| Set Time | 3-8s | 4-10s |
| Viscosity @ 60°C | 900-1600 cps | 1000-2200 cps |
| Stringing / Residue | Low stringing, cleaner edge | Medium, depends on grade |
| Thermal Stability | Stable for high-speed lines | Good, varies by resin |
| Applications | Packaging, bookbinding, electronics | Packaging, general bonding |
| Cost Efficiency | Optimized for volume supply | Competitive, depends on grade |
Which One Should You Choose?
Use jelly adhesive when you need cleaner edges, lower stringing, and more stable high-speed production. Choose EVA when standard bonding is enough and cost is the only decision factor.

Frequently Asked Questions
Direct answers for procurement managers and process engineers.
What is the difference between jelly adhesive and EVA adhesive?
Our jelly adhesives include EVA-based grades plus PA/PUR and PO/PSA families. EVA grades balance cost and fast set time for packaging and carton sealing.
When should I choose EVA versus PA/PUR?
Choose EVA for cost-effective fast-set packaging; choose PA/PUR when higher heat resistance or stronger bonding is required, such as electronics.
