Material comparison
PLA vs PET (APET)
Both make clear packaging. PLA is plant-based and industrially compostable but heat-limited; APET is petroleum-based but recyclable, tougher and heat-tolerant. The sustainability goal and use temperature decide.
PLA vs PET (APET) — side by side
| PLA | PET (APET) | |
|---|---|---|
| Source | Plant-based, renewable | Petroleum-based |
| End of life | Industrially compostable | Widely recyclable |
| Heat resistance | Low (~58 °C) | Higher |
| Clarity | High | Excellent |
| Typical use | Cold food-service, produce | Food trays, blisters, beverage |
Choose PLA when…
- Compostable, plant-based branding
- Ambient/chilled food-service disposables
- Where industrial composting exists
Choose PET (APET) when…
- Recyclable, tougher, heat-tolerant packaging
- Hot or demanding applications
- Widest recycling stream
The verdict: Choose PLA for a plant-based, compostable story on cold/ambient items; choose APET for recyclable, tougher, heat-tolerant packaging. For hot-fill or microwave, use PP instead.
Frequently asked
Is PLA better for the environment than PET?
It depends on end-of-life. PLA is renewable and industrially compostable; recycled PET (RPET) can have a strong footprint too. Match the choice to the disposal reality and use temperature.
