Compostable plastic derived from fossil fuels
Also known as
Poly Butylene Terephthalate Adipate

What is PBAT Film?

Although derived from fossil fuels, PBAT is still compostable. It's ideal for making film bags. A go-to for biodegradable plastic films. Often compared to LDPE. Commonly in packaging applications, PBAT is combined with PBAT to make a stronger compostable film.

Why choose it?

  • Often compostable in a home environment. Verify credible compostability certificates with your supplier.

  • Good ductility

  • Good resistance to heat

  • Good resistance to impact

  • Can speed up degradation of PLA when combined to create PLA/PBAT.

Why not choose it?

  • Derived from fossil fuels, a non-renewable resource

  • Not plastic-free

  • Not degradable in marine environments

  • 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.

  • 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.
