Unlike paper, which can release a significant number of particulates when a package is opened, DuPont™ Tyvek® is known for its clean peel and low-linting features. Particulate generation tests comparing Tyvek® to medical-grade papers provide conclusive evidence that Tyvek® generates far fewer airborne particulates that could contaminate the medical device or the wound site.
Particle generation test results
As tested by an internal DuPont protocol. For the particulate generation testing, samples (medical-grade papers, as well as Tyvek® 1073B and Tyvek® 1059B) were tumbled in a tumbling drum. The drum was housed in a HEPA filter lab bench. The lab bench air was filtered with two prefilters and one HEPA filter. Air was supplied by a blower with a pressure drop across the filters of 0.5 in. (1.3 cm) of water. Sampling was done with a cleanroom monitor coupled to a paper tape printer. All of the equipment was housed in a temperature-controlled, HEPA-filtered-air cleanroom that had full air exchange approximately every minute.
