What are the barrier properties of Natur-Tec resins?

Natur-Tec resins make highly breathable films compared to polyethylene films. As such the films can be used directly without the need to punch holes for breathability in some applications. This property arises naturally for all Natur-Tec resins due to the fact that these resins are biodegradable and as such absorb moisture and oxygen when in the compost environment for easy disintegration.
