PremiumCoat™, the alternative coated stopper for sensitive drugs

PremiumCoat™ is a novel range of elastomeric stoppers developed by Aptar Stelmi 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 are widening our PremiumCoat™ range introducing a 13 mm coated stopper, and will soon extend our offer with other products.
