  • Publication number: 20230201789
    Abstract: Compositions and methods for generating ClO2 gas are disclosed. A composition that includes a chlorite salt is activated by exposure to ultraviolet light. After an optional storage period, the composition is then exposed to moisture, resulting in the generation of ClO2 gas. Exemplary compositions include polymers in which the chlorite salt is dispersed. The polymers may be used to form films that can be used to package, e.g., food products, pharmaceutical products, medical devices, and/or laboratory devices. Upon exposure to ultraviolet light and moisture, the packaging releases controlled quantities of ClO2 gas, which may disinfect and/or deodorize the packaged device or product.

  • Patent number: 11224671
    Abstract: A multilayer produce packaging film includes a first layer and a chlorine dioxide-producing layer. The chlorine dioxide-producing layer includes a polymer composition and a plurality of chlorite ions. The chlorine dioxide-producing layer is substantially free of an energy-activated catalyst and is substantially free of an acid-releasing compound. However, the film is capable of generating chlorine dioxide when exposed to UV light and moisture.

  • Publication number: 20070031690
    Abstract: Multilayer film structures are disclosed having a first layer of polymer sealant material, a second layer comprising a frangible bond layer, and a third layer comprising an adhesive or polyolefin. The first layer comprises from about 1% to about 10% of the total thickness of the multilayer film structure, has a maximum thickness of about 0.25 mils. and has a thickness uniformity deviation of less than about 20% of the average thickness of the first layer.

  • Publication number: 20060065357
    Abstract: The present invention includes a continuous process for manufacturing packaging laminates adapted for easy tearing comprising the steps of providing a first and a second flexible web, applying a fluid adhesive to the first flexible web, drying the fluid adhesive, or optionally, curing the fluid adhesive, slitting one of the first and second flexible webs to form a plurality of parallel strips of at least of one the first and said second webs, and laminating the first and second flexible webs together thereby forming a laminate a plurality of parallel strips. The present invention also includes laminates form by this process.
