Post-manufacturing sterilization for results you can trust!

Your time is important and you should never worry about the validity of your test results due to a faulty sampling container, that is why our +1 Sterilization process is valuable to our customers. Whirl-Pak products undergo post-manufacturing sterilization and quality assurance testing at a medical-grade, ISO-certified facility. 

Our product differs from all others on the market by adding post-manufacturing sterilization to the process. While blowing the film, it can be assumed the closure bags are ‘sterilized’, but for added value, Whirl-Pak sterilizes product AFTER manufacturing for added assurance.

To download your digital sterility documentation, simply visit our Sterility Document Search and enter lot number captured on the carton label for immediate download.

Have you dealt with cracks in collection containers, or film bursts in other closure bags? Our exceptionally clear film makes Whirl-Pak closure bags able to withstand vigorous drop, dart and burst testing for increased reliability and durability assurance.

Currently using bottles? Not convinced a ‘bag’ can contain liquid without leaks? Experience the Whirl-Pak difference of our bags. From the secure, puncture proof tape to the Whirl, twist and tuck closure, we’ve designed our closure bags with intention to manage all liquid and solid samples from collection, transport, testing and storage.

Don’t waste time on popped-tops or leaky containers! You need a solution that can withstand impact, pressure and a broad range of temperatures. Whirl-Pak’s welded seams offer guaranteed protection and reliability.

Our design differs from all other on the market by adding the seam to the bag for the added protection against leaks our customers appreciate. 

Whirl-Pak Opening pull-tabs are designed to keep hands away from the opening of the bag to retain the sterilized state of the inner bag, assuring samples are free from contamination.

How do Whirl-Pak’s pull-tabs differ from others and help with aseptic collection? Whirl-Pak’s Tyvek® Opening pull tabs are made of non-slip, textured material and orientated perpendicular to the opening of the bag, below the tape, compared to others on the market where pull tabs are aligned horizontally overlapping the closure tape, increasing opportunity to contain the inner bag.
