One of PLA’s main limitations is its low temperature resistance. The polymer begins to deform at around 60°C, making it unsuitable for applications requiring prolonged exposure to high temperatures, such as food containers for hot liquids.
To improve this resistance, NaturePlast and its BiopolyNov R&D laboratory have modified this bioplastic by developing new PLA-based compounds through blends with other polymers and additives.
Properties
- High biobased content (> 80%)
- Biodegradable and compostable
- Food contact
- Very good temperature resistance
