| Cold-Glue (Paper) | Pharmaceuticals, Spirits | Excise stamps for tobacco products |
| Sector | Cold Glue Benefits | Hot Melt Advantages |
|---|---|---|
| Beverages | Eco-friendly, easy cleanup | Condensation resistance |
| Chemicals | N/A | Solvent-proof bonds |
| Pharma | Biodegradable adhesives | Tamper-evident seals |
| Food | FDA-compliant formulations | Freezer-grade adhesion |
Throughput: 5,000–24,000 containers/hour
Label Compatibility: Paper (70-120 gsm), film, foil
Container Handling:
Round/oval bottles Ø20–150mm
Cans, jerrycans, pails
Accuracy: ±0.5mm with laser registration
Zero-Waste Glue Application
Precision nozzles reduce adhesive consumption by 45% vs. industry average
Rapid Changeover System
Swap glue types in <20 minutes (patented purge technology)
Humidity Compensation
Automatic viscosity adjustment for tropical climates (key for Asian/African exports)
| Parameter | Glue-Based Systems | Self-Adhesive Labelers |
|---|---|---|
| Label Cost | 30-50% lower | Higher material expense |
| Throughput Stability | Superior in continuous runs | Sensitive to static/jam issues |
| High-Volume ROI | Payback <12 months | Marginally viable |
High-Speed Performance
Rotary configurations achieve 24,000 cph — ideal for beverage/dairy
Humidity Resistance
Hot-melt bonds withstand condensation (critical for refrigerated lines)
Material Versatility
Handles textured/porous surfaces where self-adhesives fail
Standard Implementation:
Inline with filling monoblocs (82% of installations)
Connected to rinse-fill-cap tri-blocks
Robust Architecture:
Minimal maintenance vs. self-adhesive peel mechanisms
97% uptime in 24/7 production environments
Application Gallery:
Beer bottles with condensation-resistant hot melt labels.
Chemical drums with permanent wrap-around bonds.
Pharma vials with tamper-evident seals.
Industry Case Studies:
Dairy Producer: 45% material cost reduction switching to hot-melt PP labels
Distillery: Cold-glue system for premium paper labels on cognac bottles
Technical Comparison Table:
| Feature | Hot-Melt PP | Cold-Glue Paper |
|---|---|---|
| Max Speed | 24,000 cph | 6,000 cph |
| Best For | Films, humid env | Textured paper, excise stamps |
