While both PET and PP offer great benefits in food packaging, choosing between them depends on the type of food you are packaging and the specific requirements of your product. Here’s a quick comparison:
| Feature | PET | PP |
|---|---|---|
| Transparency | High (clear) | Low (opaque or semi-transparent) |
| Strength | Strong and impact-resistant | Rigid but less strong than PET |
| Heat Resistance | Low to medium | High (microwave safe) |
| Chemical Resistance | Medium to high | Very high |
| Recyclability | 100% recyclable | Recyclable, but less common |
Conclusion
Both PET and PP are essential materials in the food packaging industry.
PET is great for packaging beverages, snacks, and items that require a clear, durable container with excellent shelf life.
On the other hand, PP is ideal for hot foods, microwave-safe containers, and products that require strong chemical resistance.
