PET Foaming Solution to Replace PS Foaming
Introduction
With increasingly stringent global environmental regulations and the low-carbon and recyclable transformation of the packaging industry, traditional PS (polystyrene) foaming materials are facing growing market challenges.
As a professional manufacturer of PET foaming extrusion equipment, Foshan Gaoming Keli Machinery Co., Ltd. has long focused on the R&D and industrial application of PET foaming technology. We provide one-stop solutions covering equipment selection, process development and overall plant planning, helping enterprises complete industrial upgrading from PS foaming to eco-friendly PET foaming.
1. Why PET Is Replacing PS
PS foaming materials have been widely used in food packaging, electronic cushioning packaging and building thermal insulation fields for years due to their low cost and mature processing technology.
However, with the continuous upgrading of environmental policies, the inherent drawbacks of PS materials have become prominent:
- Low recycling rate
- Brittle and easy to crack
- Difficult natural degradation
- Growing market access restrictions worldwide
- Unable to meet ESG requirements of international brand clients
In contrast, PET foaming materials deliver outstanding comprehensive advantages:
Environmental Advantages
- 100% fully recyclable
- Fully compliant with circular economy development trends
- Compatible with RPET recycled materials for production
- Meets strict European and American environmental standards
Performance Advantages
- Higher structural strength
- Superior toughness and crack resistance
- Excellent heat resistance
- Lighter weight
- Lower material consumption
Market Advantages
- Easier access to European and American high-end markets
- Higher product added value
- Fully meets procurement standards of international brands
- Greatly enhances corporate market competitiveness
2. Performance Comparison: PET Foaming vs PS Foaming
| Item | PS Foaming | PET Foaming |
|---|---|---|
| Density | 60-150kg/m³ | 50-120kg/m³ |
| Compressive Strength | Average | Excellent |
| Toughness | Poor | Excellent |
| Heat Resistance | Around 70℃ | Above 100℃ |
| Recyclability | Low | Excellent |
| Environmental Performance | Average | Excellent |
| Long-term Service Stability | Average | Excellent |
In terms of comprehensive performance, PET foaming materials have emerged as the mainstream development direction for high-end packaging and green lightweight materials.
