PE heat shrink film and stretch hood film have significant differences in many aspects, which are mainly reflected in their working principles, performance characteristics, application fields, and cost-effectiveness. Discover how these two industrial packaging solutions serve distinct purposes through different working mechanisms.
- Requires heat activation (typically 150-180°C)
- Generates shrinkage stress for tight wrapping
- Forms rigid packaging after cooling
- Room-temperature application
- Utilizes pre-stretched elasticity
- Attached to pallets without heat
| Feature | PE Heat Shrink Film | Stretch Hood Film |
| Shrinkage Method | Thermal contraction | Mechanical stretch |
| Elasticity | Moderate | High |
| Stability | Good stability after shrinkage, but unstable tension may affect the packaging effect. | High loading stability, good film elasticity, and firm packaging. |
| Safety | Fire risk potential | No ignition hazard |
| Energy Consumption | Energy consumption and pollution may be generated during the heating process. | Low noise, more conducive to recycling and disposal. |
| Display Clarity | Tight packaging after shrinkage, but general display performance. | Excellent display performance, and graphics can be printed on the film. |
- PE Shrink Film: 25-30% higher carbon footprint
- Stretch Hood: 100% recyclable, quieter operation
✓ Beverage multipacks (water/beer/cans)
✓ Temperature-resistant goods
✓ High-volume uniform loads
✓ Irregularly shaped pallets
✓ Cold storage environments
✓ Retail-ready displays (printed graphics)
✓ Pressure-sensitive products
- Higher energy costs ($0.15-0.20/pallet)
- Faster degradation under UV
- 40% lower energy consumption
- 15-20% faster packaging speed
- Better load stability (reduces damage by 30%)
Consider these factors:
1. Product Sensitivity: Heat/weight limitations
2. Throughput: High-speed vs precision needs
3. Sustainability Goals: Carbon/energy priorities
4. Display Requirements: Printing/visibility
