FluroTec? Barrier Films – Protecting Your Biologics

There is no doubt biologics and biosimilars will remain one of the hot topics in 2021. This is due to the pandemic period of SARS-CoV-2 and the innovative treatments and vaccines that are under development at accelerated speed. Several questions can arise regarding selection of the proper primary package system for a biologic/biosimilar.

Ready Pack System

Some common questions that arise frequently are:

  • The biologic is very sensitive, can the system provide enough protection?
  • The molecules are very complex, can the system maintain stability?
  • The timeline for approval is very tight, will the system be approved?

These questions are especially challenging for a company that may have expertise in drug development, but not primary package systems.West can help. Based on extensive knowledge and a history of market leadership, West offers primary packaging systems that can address these and other questions. An example is the Ready Pack™ system, which comprises NovaPure® stoppers, Flip-Off® CCS (clean, certified, sterilized) seals, and Schott adaptiQ® glass vials. In particular, NovaPure stoppers have a FluroTec™ barrier film in areas that contact drug product. This film, based on poly(ethylene tetrafluroethylene), provides added protection by reducing:

  • migration of leachables from elastomer into drug product
  • interaction of drug products with stoppers

Each NovaPure stopper is vision inspected using the Envision™ verification process to ensure low and controlled particle levels. Ready Pack system components are offered in quantities that support every development stage – from concept through commercialization. They may be a very good choice for biologics and biosimilars. For more information, contact an Account Manager or Technical Customer Service representative.
