  • Publication number: 20140311094
    Abstract: The presently disclosed subject matter relates generally to methods of generating at least one disinfecting gas within a package through a photochemical reaction. More particularly, the disclosed methods include incorporating a composition capable of generating a gas upon exposure to light into the disclosed package. As set forth in detail herein below, the amount of moisture present in the disclosed composition is directly related to the production rate of the gas. Accordingly, the amount of gas generation can be controlled by varying the amount of moisture present in the composition.

  • Patent number: 8252396
    Abstract: The presently disclosed subject matter is directed to a barrier film that maintains an oxygen barrier after being subjected to autoclaving conditions. The film comprises one EVOH layer positioned as a core layer, and one EVOH layer positioned directly adjacent to an outer layer comprising highly permeable material having a moisture vapor permeability greater than about 40 g-mil/100 in2-day-atm. During autoclaving, the barrier properties of the EVOH layer positioned adjacent to the outer layer allows improved recovery of oxygen barrier properties. In addition, during rewetting applications, the internal EVOH layer maintains the oxygen barrier. Also disclosed are methods of making and using the disclosed barrier film.

  • Publication number: 20110127188
    Abstract: The presently disclosed subject matter is directed to a multilayer coextruded film that can be used in combination with uncoated medical grade paper or uncoated Tyvek® to produce a sterile barrier system that delivers desired seal and peel characteristics with no paper tear. The combination can be particularly suitable for medical device packaging where the package is subjected to gas sterilization, such as with ethylene oxide.
