Comparison of Different Materials: PLA, Cornstarch, and Traditional Plastics
1. PLA (Polylactic Acid)
PLA is derived from renewable resources such as corn. It has high transparency and an appearance similar to traditional plastics, making it suitable for products like salad boxes and cold drink cups. Its main advantage is strong compostability, meeting European and American environmental standards.
2. Cornstarch Material
After modification, cornstarch material has strong heat resistance (above 90°C), making it suitable for hot food applications such as takeaway containers. It also performs well in oil resistance, water resistance, and structural strength. It is currently one of the fastest-growing materials in the food containers wholesale market.
3. Traditional Plastics (PP/PS)
Traditional plastics are low-cost and stable in performance, but they are not biodegradable and are increasingly restricted by global policies.
| Comparison Dimension | PLA | Cornstarch | Traditional Plastics (PP/PS) |
|---|---|---|---|
| Heat Resistance | Low (50–60°C) | High (90°C+) | Very High |
| Environmental Property | Compostable | Biodegradable | Non-biodegradable |
| Cost | Medium to High | Medium | Low |
| Application Scenario | Cold food, display packaging | Takeaway, hot food | Traditional catering |
| Policy Trend | Supported | Supported | Restricted |
