Vacuum Blister Materials Science Center
Comprehensive material data and selection guide to help you choose the most suitable blister material for each project.
Material Database
Filter the most suitable blister materials according to performance, application or process requirements
Acrylic（PMMA）
- Transparency 98%
- Strength 80%
- Flexibility 50%
- Heat Resistance 80%
High transparency, high surface hardness, weather resistant
Typical applications: High-end light boxes, signage, display racks, skylights
The material is relatively brittle and prone to cracking, but has excellent transparency.
PET (A-PET)
- Transparency: 90%
- Strength: 85%
- Flexibility: 75%
- Heat Resistance: 70%
Food-grade, environmentally friendly, high strength
Typical applications: High-end blister packs, food packaging, electronic products
High-frequency heat sealing is difficult; often solved by laminating with PVC film (i.e., PETG).
The Influence of Process on Material Selection
Different vacuum forming processes have specific requirements for material properties; selecting the right material is crucial for success.
Process and Material Matching Guidelines
The choice of vacuum forming process directly affects material performance and final product quality. Below are key process factors and corresponding material selection recommendations:
Die forming
Process characteristics: High product appearance precision and excellent surface detail reproduction
Recommended materials: ABS, PMMA, PC; these materials can perfectly replicate mold textures.
Wall thickness control: High material ductility is required; PETG and flexible PVC are recommended.
Punch forming
Process characteristics: Accurate internal dimensions and relatively uniform wall thickness
Recommended materials: PP, PS, HIPS, with stable shrinkage rates.
Precautions: Avoid using highly elastic materials, as they may cause demolding difficulties.
Gas-assisted molding
Process characteristics: More uniform wall thickness, suitable for deep cavity products
Recommended materials: PETG, PC, certain engineering plastics
Advantages: Allows the use of materials with higher melt strength, reduces wall thickness variations
Professional Advice
For molds with complex structures and small demolding angles, it is recommended to use specialized sheets with better elasticity. This not only improves the demolding effect but also extends the mold’s lifespan. For deep-cavity products, materials with excellent ductility should be selected, or pre-stretching technology should be used in the manufacturing process.
Material Selection Guide
Choose the most suitable thermoforming material based on application scenarios and performance requirements.
| Application Scenario | Preferred Materials | Alternative Materials | Key Consideration Factors |
|---|---|---|---|
| Food Packaging | PP (heat resistant), PET (transparent / barrier) | Food-grade PVC, APET | Food safety certification, temperature resistance, transparency |
| Electronics Industry | PVC / PS (inner trays), ABS (outer housings) | PETG, antistatic PS | Antistatic performance, mechanical strength, cost efficiency |
| Medical Devices | PETG (sterilized packaging), PP (instrument trays) | PC, medical-grade PVC | Biocompatibility, chemical resistance, sterilizability |
| Automotive Interior | ABS (structural frames), PVC (surface layers) | Modified PP, ASA | Weather resistance, UV resistance, dimensional stability |
| Retail Display | PMMA (high transparency), PETG (durable) | PVC, PS | Optical clarity, surface hardness, aesthetic appearance |
| Industrial Components | ABS, PC (high strength) | HDPE, PA (nylon) | Mechanical strength, chemical resistance, dimensional accuracy |
