Abstract
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.
Claims36
A container comprising:
- a wall made of a cycloolefin polymer having an internal surface enclosing a lumen and an contact surface, and
- an external anti-static and anti-scratch coating on the contact surface,
- wherein the external anti-static and anti-scratch coating is optionally an inorganic-organic hybrid polymer coating comprising an anti-scratch agent and an anti-static agent.
Dependencies are inferred from the claim text.
