PremiumCoat™ The alternative coated stopper for sensitive drugs
PremiumCoat™ is a novel range of elastomeric stoppers developed by Aptar Stelmi launched earlier this year. Based on an approved, pure, state-of-the-art formulation, the surface of the elastomer is coated during manufacturing with an ETFE 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 with PremiumCoat™ stoppers.
