The Role

As an Intern in Packaging Development in R&D team, you will play a crucial role in our mission to protect the planet by developing materials for clean and closed material loops. You will have the opportunity to engage in hands-on tasks such as conducting experiments, analyzing data, and assisting in the research and development of innovative sustainable packaging solutions. Drawing on your theoretical background in material science, engineering or applied chemistry, you will contribute to the design and optimization of experiments, while gaining valuable practical experience in a laboratory setting.

How you'll help build one

  • fıve Areas of ownership

Research and Laboratory Operations Support:

  • Assist in ongoing experimental plans aimed at developing packaging solutions for clean and closed material loops. Familiarity with heat seal, and barrier polymer-based layers is nice to have.
