Gerresheimer launches multilayer COP/PA/COP vials for pharmaceuticals

Gerresheimer (Düsseldorf, Germany) has developed cyclic olefin polymer (COP) multilayer vials for sensitive parenteral medicines, saying the material offers barrier properties that are unique for plastic. Launched by the company at Pharmapack (Paris; Feb. 1-2), the triple-layer structure vials can be used for cytostatics and biopharmaceutics. In addition to being thermally and mechanically durable, Gerresheimer says that in comparison to competitive plastic, COP's inert surface has a lower propensity to adsorb proteins, while the oxygen barrier is "among the best in the field of plastics," according to the company.

The injection molded vials consist of two COP outer layers with a middle layer of polyamide. The materials satisfy biocompatibility and pharmacopoeia requirements for a pharmaceutical primary package made of plastic. The company says the multilayer vial can also be combined with standardized rubber closures and flanged caps. Gerresheimer plans to supply multilayer vials that are sterile and ready to fill, similar to its RTF and Clearject syringes.

Last September, Gerresheimer AG CEO Axel Herberg stressed the importance of plastics for the company going forward, when it announced a new research and development center for medical plastic systems in Peachtree City, GA as well as a new production center for pharmaceutical plastic packaging in Masalavés, Spain. "Plastics are increasingly gaining in importance within our highly specialized service portfolio for the international pharmaceutical industry," Herberg said. —[email protected]
