摘要:
The presently disclosed subject matter provides a package and methods for disinfecting a wide variety of microbiologically contaminated products. Particularly, the disclosed package comprises a package to house the product to be disinfected and a disinfecting gas generator positioned within the interior of the package. The materials used to construct the package and/or the gas generator comprises an active agent that neutralizes the disinfecting gas from the interior of the package. The reactivity of the active agent is balanced such that the rate of neutralizing is lower than the rate of disinfecting gas release. As a result, the disinfecting gas has time to function fully before it is neutralized. Thus, when a user opens the package at the end of the disinfecting period, exposure to the disinfecting gas is minimized or eliminated.

Barrier coating mixtures contain in a carrier liquid, (a) an elastomeric (preferably butyl-containing) polymer; (b) a dispersed exfoliated layered filler having an aspect ratio greater than 25; and (c) at least one surfactant, wherein the solids content of the mixture is less than 30% and the ratio of polymer (a) to filler (b) is between 20:1 and 1:1. Coated articles, which are rigid or flexible and elastomeric, and free-standing films and membranes, which are flexible and elastomeric, are produced using the barrier coating mixtures.

摘要:
An article, such as a polymeric film, sachet, purge control pad, or label, includes a sulfur scavenger. In some embodiments, an oxygen scavenger is also included. A method includes providing an article, including a sulfur scavenger and an oxygen scavenger; and subjecting the article to a dosage of actinic radiation effective to trigger the oxygen scavenger. A method of reducing the sulfur content of a package containing a food product includes either (1) providing a film including a layer including a zinc ionomer, and a layer including an oxygen scavenger; packaging the food product in the film; and storing the package for at least 24 hours; or (2) providing the food product at a temperature of 40° F.; providing a film including a layer including a sulfur scavenger; packaging the food product in the film; and storing the package for at least 24 hours.

A method of increasing the gas transmission rate of a packaging film comprises providing a packaging film that comprises at least about 0.001 weight % of single-walled carbon nanotube material based on the weight of the film. The packaging film is exposed to an amount of radiation energy effective to increase the oxygen transmission rate of the packaging film by at least about 100 cc (STP)/m2. day (1 atm, 0% RH, 23° C.).

摘要:
An intercalated layered silicate comprises a layered silicate and an intercalating agent sorbed between the silicate layers of the layered silicate. The amount of intercalating agent is effective to provide an average interlayer spacing between the silicate layers of at least about 20 Å. The intercalating agent has a formula selected from formulas I through VII described herein. The intercalated layered silicate may be exfoliated by mixing it with a matrix medium and adding sufficient energy to form a dispersed-particle composition. A packaging film, such as a food packaging film, may comprise the dispersed-particle composition.
