PremiumCoat™ is a novel range of elastomeric stoppers developed by Aptar Pharma and based on an approved, pure, state-of-the-art formulation.
The surface of the elastomer is coated during manufacturing with a thin fluoropolymer film.

This coating acts as an effective barrier to many of the extractables and leachables that can be released from the elastomer. As a result, compatibility of the drug and the closure is significantly superior.

The first design to be released in 2015 was a 20 mm coated stopper. We widened our PremiumCoat™ range introducing a 13 mm coated stopper in 2016, and we are now extending our offer with our 1 mL plunger.
