Packaging & Availability

Packaging Type
Packaging Information

Biodegradable polymers must be packaged to strict requirements in order to be protected from degradation by moisture. At Evonik, we package our polymers in heat-sealed polyethylene bags under high-purity nitrogen. These polyethylene bags along with a desiccant pouch are heat-sealed into foil-laminate outer bags. All packaging is performed in a clean room. We also offer special packaging, such as multiple containers or alternative sizes, to support your production and R&D needs.

Storage & Handling

Shelf Life
max. 3 months
Storage Conditions

The packaged polymers are labeled for storage at ≤ -10 °C.
