The PSM Advantage

Biodegradable PSM offers many advantages over conventional petroleum based plastics and alternative compostable manufacturing materials. The table below highlights just a few, including degradation characteristics, oil resistance, and tempurature performance. As an example, PSM even allows you to thermoform food containers that are mircrowavable yet completely biodegradable.
