Reducing single-use plastic waste in the pharmaceutical industry with pulp-made injection caps.
Given the strict hygiene requirements, massive amounts of single‑use trays and components made from virgin plastics are consumed in the pharmaceutical industry.
Pulp‑Injection could be a more sustainable alternative.

In the pharmaceutical industry, the move to reduce plastic use in secondary packaging is gradually expanding.
This trend is expected to move into device components as well.
The initial focus was the development of a cap for an autoinjector.
A critical requirement was to ensure reliable locking and protective functions to prevent accidental removal and avoid misfires.
These features are achieved through Pulp-Injection technology by incorporating internal ribs within cylindrical geometries, creating a distinct click-feel when the cap is opened and closed. This level of precision is made possible by the injection-molded process, which clearly differentiates Pulp-Injection from other pulp-based materials.
Although Pulp‑Injection uses injection molding, that doesn’t mean the same shapes can be molded the same way as with conventional plastics. By taking on the challenge of developing a new mold structure, we succeeded in forming this difficult “deep cylinder” shape and achieving a clear click‑feel, which was more complex than the geometries typically produced with Pulp‑Injection. This project received the Packaging Innovation Award at Pharmapack Awards 2024. It was recognized not only for successfully recreating the shape of a conventional plastic injection‑molded part, but also for delivering comparable functional performance while significantly reducing the use of petroleum‑based plastics.
