Aluminum Plate Protective Film Impact Resistance
Factors affecting performance and evaluation methods
1. Material Difference
- PET material: High strength, good toughness, excellent impact resistance, effectively buffers impact
- PE material: Relatively soft, weak impact resistance, mostly for light protection
- Acrylic composite: Combines high hardness and toughness, performs well against sharp object impacts
2. Structural Design
- Multi-layer composite structures significantly improve impact resistance
- Functional layers like buffer layers and wear-resistant layers work together
- EVA buffer layers disperse impact force and reduce aluminum plate damage
3. Thickness Influence
- Thicker films generally offer stronger impact resistance
- 0.1mm films resist slight collisions only
- Films >0.3mm withstand greater impact but may affect processing accuracy
4. Process and Additives
- Hardened films increase surface hardness and impact resistance
- Impact modifiers enhance flexibility and resilience
- Special additives reduce damage from external impacts
5. Performance Testing
- Simulate impacts through drop ball tests
- Observe film damage and aluminum plate surface condition
- Review supplier impact resistance test reports
Testing Recommendation
Evaluate product performance under different impact intensities to select the most suitable aluminum plate protective film for your application requirements.
