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.
