“PremiumCoat sets the standard for film-coated stoppers with an unrivalled reduction in particulates: achieving a market-leading Particulate Count Index of 1.3…”

For over 50 years Aptar Pharma’s injectables specialists have led the way in developing innovative elastomer solutions. Their commitment to continuous improvement has resulted in elastomer formulations that feature best-in-class extractables and leachables profiles.

As the pharmaceutical market continues to develop ever more sensitive drugs, including biotherapeutics, the need for improved regulatory requirements increases. Aptar Pharma has risen to the challenge, delivering the highest standard of cleanliness in elastomer components. Aptar Pharma’s focus for both the last 12 months and the foreseeable future is quality: in R&D, customer insight and product solutions.

Aptar Pharma was the first company to provide a Drug Master File (DMF) for the Ready-to-Sterilise (RTS) process, as well as the first company to provide Ready-to-Use (RTU) stoppers to the market – a quality standard now seen as the norm. With future commitment to quality in mind, Aptar Pharma has developed the Premium portfolio of injectable components.


The Premium portfolio delivers cleaner components to satisfy the ever-increasing demands of the pharmaceutical industry for inert stoppers; particularly in the delivery of more sensitive and expensive drugs, including complex proteins.

PremiumFill® is a RTS process, prior to container filling, with specifications guaranteed to Aptar Pharma’s highest quality of production, resulting in lower embedded particles, improved particulate cleanliness, and an overall reduction in defects.

All PremiumFill® manufacturing is in-line, reducing the risk of contamination during transport around the plant, thus avoiding adding intermediate storage steps in a classified manufacturing area.

PremiumCoat sets the standard for film-coated stoppers with an unrivalled reduction in particulates: achieving a market-leading Particulate Count Index (PCI) of 1.3, compared with the historic standard of 2.9. The coated stopper features a fluorinated polymer film (ETFE), which is applied during the manufacturing process. This approach delivers a homogenised coating, which is the established best practice method, to create the most robust and effective barrier between the drug and the stopper (Figure 1).

PremiumVision is a guaranteed quality commitment using an in-line, automated vision system. PremiumVision is designed to further validate against critical defects.


The challenge to deliver higher standards of cleanliness in elastomer components is driven both internally and externally. As ever more complex and expensive drugs are developed, there is an absolute need to ensure that a stopper’s integrity is guaranteed. The Premium Portfolio’s commitment to lowering particulates provides for the highest standard level of guaranteed specification for laminated stoppers in the market today, meaning even greater levels of reassurance for the customer.


There are several key advantages of PremiumCoat, most notably its aforementioned 1.3 PCI and Aptar Pharma’s deep experience in delivering gamma-irradiated stoppers. For several years Aptar’s injectables specialists had focused solely on developing elastomer formulations with extremely low extractables profiles, to the point where they are the cleanest available on the market today.

“Aptar Pharma will introduce the latest developments in its Premium Portfolio when it exhibits at CPhI Worldwide in October…”

Whilst non-coated stoppers are still the component of choice for many drug formulations, there is an increasing need for the additional level of reassurance provided by coated stoppers. PremiumCoat’s homogenised ETFE coating results in a barrier which is both more effective and easier to inspect with automated vision systems. The process also ensures that only the area that comes into contact with the drug is treated, guaranteeing closure with the vial.

The Ready-to-Sterilise product, PremiumCoat is designed for organisations that have sterilisation facilities in place. It is compatible with steam sterilisation and uses Aptar Pharma’s proprietary washing process. The Ready-to-Use version comes already gamma radiation sterilised, providing the customer with convenience and flexibility. This approach leads to a reduction in the number of human operations as well as improved productivity, as the stoppers may be used immediately and can be directly used in RABS or isolators. There are significant economic advantages too in terms of a reduced investment in equipment required, negated maintenance costs and reduced stock levels.


Aptar Pharma will introduce the latest developments in its Premium Portfolio when it exhibits at CPhI Worldwide in Frankfurt in October. In addition to exhibiting at CPhI, Arnaud Fournier, Aptar Pharma’s Senior Business Project Manager, will be delivering a Pharma Insight Briefing entitled “Setting New Standards for Coated Stoppers”. His presentation will take place on day two of CPhI.
