Health kick: advances in medical materials
Production standards for medical materials typically exceed those of other industries – including food. Despite the challenges of developing new materi- als in this sector, suppliers continue to find new ways to meet the needs of medical companies. Constantia Flexibles says that its Perpetua and
Perpetua Alta flexible packaging sachets offer a high barrier to keep the contents safe. It says that, because they are a mono-material solution (all-polypropylene), they are easier to recycle. Constantia showed the sachets at the Pack Expo International show in Chicago last year. “In our R&D department we place equal impor- tance on the safety and sustainability of our packag- ing,” said Pim Vervaat, CEO of Constantia Flexibles. “Our packaging is only fit for the future if it meets both our standards. With Perpetua and Perpetua Alta, we combine performance and sustainability.” Perpetua protects against oxygen, water vapour, and light – which is necessary to maintain the

efficacy of medicines. In addition, it is Cyclos-HTP certified, meaning it has a recyclability of 90-96%, depending on the individual material specification. Perpetua Alta has a high chemical resistance to pharmaceutical products, so can be used for more demanding products (in both pharmaceuticals and foods). Compared to conventional laminates, the package is lighter, with higher efficiency, and offers optimal protection, says Constantia. Constantia also invests in counterfeit-proof
packaging – because up to 30% of the world’s medicines are counterfeit, it says. Many of Constan- tia’s product lines are available with anti-counter- feiting features.
