Compostable plastic derived from a mix bio-based materials and fossil fuels.
Also known as
Polylactic Acid, Polylactide

What is PLA/PBAT Film?

PLA is primarily derived from renewable resources (usually corn), while PBAT is derived from fossil fuels. While PLA is strong, it’s brittle and rigid. When PBAT is added to create PLA/PBAT, the combined materials are flexible and strong.

Adding PBAT to PLA also speeds up degradation time and lowers the required temperature which can make home composting certifications available.

Why choose it?

  • May be compostable in home or industrial settings, depending on the ratio of PBAT to PLA. Verify credible compostability certificates with your supplier.

  • Mix of renewable and non-renewable resources

  • Gloss and matte finish options

  • Waterproof

  • Good solvent resistance

Why not choose it?

  • Not completely plastic-free (contains petroleum-based additive PBAT for flexibility)

  • Many consumers do not have access to industrial composting.

  • Some composting facilities will not accept compostable plastics, because they can slow down their composting cycles.

  • It cannot be recycled, but because it looks and feels like traditional plastic, it often ends up recycled with plastic. This contaminates and slows down the recycling stream.

  • Requires adequate messaging for proper disposal. If compostable plastics end up in landfills, they will take much longer to degrade (can be decades) without the right amount of heat, moisture, and oxygen to attract the microbes necessary for degradation.
