B+K CleanFlex® Tyvek®/HDPE Bags

The combination of a PE bag with 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 Tyvek® and the rear from HDPE; however, full Tyvek® packaging material is also possible, as is the integration of a Tyvek® window.

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 confirms that water vapour sterilisation has taken place.
