Gerresheimer Introduces New COP Multilayer Vials

COP (Cyclic Olefin Polymer) is a heavy-metal-free plastic that Gerresheimer has also used for sterile syringes over many years. It has specific advantages which makes it particularly suitable for the demanding field of cytostatics and biopharmaceutics. It is thermally and mechanically very durable and in comparison with other relevant plastic types, its inert surface has a much lower propensity to adsorb proteins, for example. The oxygen barrier properties are among the best in the field of plastics, said the company.

With the new development, the injection specialists in Gerresheimer Buende have now succeeded in substantially enhancing these barrier properties even further (to several times that of vials consisting of COP alone), by combining two COP outer layers with a middle layer of polyamide.

This material, as the company said, meets the highest demands in terms of biocompatibility and naturally all the pharmacopoeia requirements for pharmaceutical primary packaging made of plastic. In addition, it can easily be combined with standardized rubber closures and flanged caps. The vials are consistently designed in accordance with the ISO standard.
