Bio-based plastics in pharma: are injection molds ready?
The introduction of bio-based polymers in pharmaceutical packaging is opening up new industrial scenarios. These emerging materials require a thorough rethinking of injection molding processes: cycle times, thermal control, filling behavior and part geometry must be recalibrated.
For specialists in multi-cavity molds and high-precision components for the medical packaging sector, this represents a technical evolution that cannot be overlooked. Even if not yet widely adopted, bio-grade materials for pharmaceutical use demand design readiness.

Giurgola Stampi’s technical portfolio already includes up to 72-cavity molds for tamper-evident capsules, Ø18 mm screw caps, and child-proof systems—optimized for transparent, rigid, or high-barrier resins.
This provides a solid technological base for adapting to bio-based materials. Thanks to our expertise in injection mold design—including hot tip systems and motorized unscrewing units—our molds can be adjusted to match the different flow and cooling properties of new materials while maintaining reliability and dimensional accuracy. This is where co-design with pharma partners becomes a key differentiator.
In pharmaceutical packaging, there is zero tolerance for dimensional or functional deviation. Whether working with standard polymers or bio-materials, every mold must guarantee repeatability for complex geometries and tight tolerances.
While full-scale adoption of bio-polymers in pharma is still in progress, Giurgola Stampi already offers preliminary testing cycles with alternative resins, supported by Moldflow simulations, industrial CT scans, and real-world trials on servo-electric presses. This forms a solid foundation for anticipating industry needs—where tomorrow’s packaging will be smarter, more functional, and compatible with automated dispensing systems.
Sources like Matrec further underline the pharma industry’s interest in high-performance, non-traditional materials. These developments clearly show that injection mold technology must be ready for precision-driven adaptations and high-level technical interaction between mold, machine, and material.
