Designed for steam sterilization processes of single use medical devices that require strong mechanical protection, with a target event related sterility maintenance of up to 3 years, Polybond-S 112 gsm associates medium to high seal strength levels to efficiently withstand vacuum cycles during sterilization, controlled maximum pore size for highest possible safety in sterility maintenance after sterilization, and very good mechanical performance in dry and wet stages thanks to polymer reinforcement of web material to maintain physical protection of your medical device. 


Polybond-S 112 gsm has been developed to seal to PA/PP films for the packaging of single use medical devices such as pre-filled syringes as well as the segment of industrial steam sterilization businesses where Tyvek packaging material is currently being used
