PET Folding Box UV Curable Adhesive is a premium one-component, solvent-free UV-curable adhesive specially formulated for bonding PET folding cartons, transparent plastic boxes, cosmetic packaging, food containers, electronic product packaging and premium display boxes.
The adhesive cures instantly under UV LED or traditional UV lamps, delivering exceptional transparency, high initial bonding strength and outstanding production efficiency. It is designed for fully automatic folding and gluing machines, helping manufacturers achieve faster production speeds while reducing operating costs.
Compared with conventional solvent-based adhesives, this UV adhesive offers cleaner processing, higher productivity and superior long-term durability.
| Domain | Parameter | Technical Specification | Industrial Performance Standard (行业表现标准) |
|
1. Nature |
Chemical Type / Basis | Modified Acrylic Resin | 100% reactive monomer & oligomer blend, solvent-free. |
| Appearance / Color | Clear, Colorless Liquid | Ensures crisp, invisible seam lines on high-clarity boxes. | |
| Viscosity (at 25°C) | 60 – 150 cps | Low viscosity for high-speed jetting without tailing or stringing. | |
| Density | 1.05 – 1.10 g/cm³ | Consistent volumetric dosage control during continuous manufacturing. | |
| Solid Content | ≥ 99% | Zero shrinking after cure, avoiding structural box deformation. | |
|
2. Next-Gen Curing |
Recommended Wavelength | 365nm + 395nm (Dual Spectrum) | 365nm for tack-free surface; 395nm for deep PET penetration. |
| Required Curing Energy | 300 – 600 mJ/cm² (UVA) | Optimized molecular cross-linking to eliminate uncured adhesive. | |
| Minimum UV Intensity | ≥ 150 mW/cm² | High power density required for instantaneous structural lock. | |
| Cure Speed / Cycle Time | 1.0 – 3.0 seconds | Supports automated box-folding line speeds up to 40–60 m/min. | |
|
3. Nirvana Quality |
Adhesion on Untreated PET | 5B (ASTM D3359 Grid Test) | 0% peel-off; structural failure occurs within substrate itself. |
| Elongation at Break | ≥ 120% | High elasticity prevents glue line snapping from box tension. | |
| Shear Strength (PET to PET) | ≥ 4.5 MPa | Heavy-duty loading capacity; cross-border transport secure. | |
| Optical Transparency | ≥ 98% | Blends seamlessly into clear PET films with zero fogging. | |
|
4. Network Stability |
Yellowing Resistance | ΔE < 1.5 (168h UV Aging) | Resists color degradation under prolonged retail display lighting. |
| Thermal Shock Endurance | -20°C to +70°C (48h Cycle) | Prevents automatic pop-open in extreme shipping containers. | |
| Damp Heat Resistance | 60°C / 95% RH for 72 Hours | Anti-hydrolysis polymer backbone ensures long-term seam integrity. | |
| Shelf Life | 12 Months | Stable formulation when stored at 5°C–25°C in opaque containers. |
