Unleash the power of our Pressure-Sensitive Adhesive (PSA), a revolutionary bonding solution that adheres quickly with just a light touch, bypassing the need for solvents, heat, or additional curing. Crafted for excellence in labeling, packaging, and a variety of industrial and commercial applications, this PSA provides robust adhesion, unmatched durability, and exceptional adaptability to environmental conditions. Its versatility shines through in applications such as labels, tapes, protective films, decorative stickers, and beyond.
Instant Adhesion
Bonds firmly with light pressure, suitable for both automated labeling and manual application.
Wide Substrate Compatibility
Adheres to various surfaces (plastic, glass, metal, paper, wood, etc.).
Environmental Resistance
Temperature range: -20°C to 80°C; UV-resistant, moisture-proof, with some models offering water/oil resistance.
Customizable Adhesion
Available in permanent, removable, or repositionable grades to meet diverse needs.
Eco-Friendly & Safe
Complies with RoHS/REACH standards; some products are solvent-free (water-based or hot-melt formulations).
3. Common Types of Hot Melt Adhesives
| Type | Advantages | Limitations | Typical Applications |
|---|---|---|---|
| EVA-Based (Ethylene-Vinyl Acetate) |
• Low cost • Excellent paper adhesion |
• Low heat resistance (Softening point: 60-80°C) |
Paperback books, magazines |
| PUR (Polyurethane Reactive) |
• High heat resistance (up to 120°C) • Superior flexibility |
• Moisture-curing required • Higher equipment costs |
Hardcover books, premium editions |
| APAO-Based (Amorphous Polyalphaolefin) |
• Outstanding elasticity • Fatigue resistance |
• Higher material cost | Lay-flat books, frequently opened manuals |
4. Key Process Parameters for Adhesive Application
Optimal Range: Maintain precision with a temperature spectrum of 150-180°C for EVA-based adhesives.
Critical Note: Beware of excessive heat! Temperatures surpassing 200°C can degrade polymers, weakening bond strength by over 30%.
| Method | Technical Specification | Equipment |
|---|---|---|
| Roll Coating | 0.1-0.3mm glue layer thickness ±5% uniformity requirement |
Glue roller systems |
| Spray Application | 50-100μm droplet size Requires 0.3-0.6MPa air pressure |
PUR-specific spray heads |
Milling: Perfect the spine edge by removing 0.5-1.0mm at a 45° angle for optimal adhesion.
Roughening: Achieve a 20-30% increase in porosity with 60-80 grit sanding.
Pre-heating: Elevate surface temperature to 50-60°C for superior adhesive wetting.
Process Validation Metrics:
✓ Ensure adhesive penetration depth reaches a minimum of 0.4mm for maximum efficacy.
✓ Achieve binding strength of at least 35N/cm, as per the ISO 15754 standard.
Note: Different adhesives like EVA and PUR require varied spine roughness profiles. Please refer to our comprehensive technical guide for specific parameters.
