Cycloolefin polymer (COP) containers, including vials or syringes, having a scratch-resistant and anti-static coating on the external wall results in a reduction or prevention of static charge on the articles. The combination of an anti-scratch and anti-static coating results in the reduction of the attraction of charged particles to the container, leading to decreased particulate contamination while providing scratch resistance.
