B+K CleanFlex® Tyvek®/HDPE Bags

B+K CleanFlex® Tyvek®/HDPE Bags

The combination of a PE bag with DuPont™ Tyvek® material enables the product to be sterilised using water vapour through the surface of the packaging material. As a rule, the front is manufactured from DuPont™ Tyvek® and the rear from HDPE; however, full DuPont™ Tyvek® packaging material is also possible, as is the integration of a window made with DuPont™ Tyvek®. Our so called "SteriBags" are therefore perfectly made for steam sterilization.

Plastic and rubber bungs can be sterilised using water vapour in the bag, without its subsequently having to be re-opened. The seals can be used directly.

By changing colour, a printed-on sterility indicator on the SteriBags confirms that water vapour sterilisation has taken place.
