Abstract
The present invention relates to a method for sterilizing an article inside a sealed container by placing a polyoxymethylene melt formable co-polymer fiber that has been irradiated between about 1 and 200 kGy and then heated at from about 20° C. to about 90° C. for a selected period of time.
Claims13
A container of a selected volume on the inside suitable for low heat sterilizing a selected article positioned in the inside of the container comprising:
- a container insert in the selected volume on the inside of the container comprising a melt blown fiber of a diameter 0.5 mm or less of polyoxymethylene or co-polymer of polyoxymethylene having a melt flow rate of between about 20-1200 g/10 minutes at 230° C. as determined by ASTM D1238E that has been irradiated with gamma ionizing irradiation from about 1 to about 200 kGy wherein the polymer is of sufficient quantity to produce a concentration of formaldehyde sufficient for complete sterilization of the article in the container.
