This co-injection technology makes it possible to combine different layers of material into a single part, optimizing properties such as mechanical strength and barrier performance, while increasing the percentage of recycled content incorporated (from 15% to 30%). This process represents a breakthrough in the industrialization of circular packaging solutions, enabling the scaled-up production of more sustainable plastic packaging without compromising its functionality. It also helps reduce dependence on virgin plastic, meet European targets for incorporating recycled material into packaging production, and maintain the quality and performance standards required for food applications.
