Klöckner Pentaplast introduces new film to its Pentamed film line.

The Pentamed film product line from Klöckner Pentaplast now includes Pentamed MD-EK10R00, a high-performance rigid co-polyester film designed for medical-device packaging applications.

This new film fills an unmet need in the industry for increased toughness and temperature performance for demanding medical form-fill-seal and tray applications. Ideal for packaging heavy medical equipment and frozen products, Pentamed MDEK10R00 films are available worldwide.

The Pentamed MD-EK10R00 films have a high glass-transition temperature that allows for heat resistance to slow aging and provide speed validation and sterilization. Quicker accelerated-aging protocols are possible as faster and more reliable shelf-life qualification can reduce time, labor, and speed-to-market delays.

The films have slower aging properties and, therefore, provide for an increased shelf life.

Additionally, higher sterilization chamber temperatures are not limited by the package so there is faster EtO (Ethylene oxide) cycle time and reduced risk of warping and sticking. For every 10°C increase in EtO chamber temperature, sterilization time can be reduced by half—allowing for a substantial cost savings for large volume OEMs (Original Equipment Manufacturers).

Demonstrated by notched Izod-impact, dart-impact, and aged internal-drop tests, Pentamed MDEK10R00 films are proven tough via third-party packaging validation tests following three rounds of EtO sterilization. This robust and durable film protects sterilized contents against damage and breach of sterile barriers adding to its increased shelf life. Due to the toughness of this film, the redesign of packaging to reduce material usage through downgauging or lightweighting is possible as is the need for secondary packaging.

“Pentamed MD-EK10R00 high-performance co-polyester films were developed to address an unmet industry need for increased toughness and temperature performance,” explains Justin Glass, Klöckner Pentaplast’s business manager for medical device films in the Americas. “The expansion of our medical-device product range to include these films, along with our existing Pentamed film line, continues to provide our customers with the broadest available selection of films in the industry.”
