Abstract:
A method for triggering an oxygen scavenging composition for use in packaging an oxygen sensitive article includes the steps of providing an oxygen scavenging composition including an oxidizable organic compound, and exposing the composition to a source of pulsed light wherein each pulse has a duration of between 1 microsecond and 1 millisecond, a frequency of between 0.1 to 100 Hertz, and an intensity of at least 350 mW/cm2 so that each pulse provides the composition with a dose of UV light of at least 0.1 J/cm2 so as to provide a triggered composition. The triggered composition can be applied to an article so as to provide an oxygen scavenging package. An apparatus and packaging system are also disclosed.

Abstract:
A method of initiating oxygen scavenging by compositions which comprise oxidizable organic compounds and transition metal catalysts is disclosed. The method comprises initiating scavenging by exposing the composition, etc., to radiation. The radiation exposure is preferably electron beam or ultraviolet light and is preferably used on oxygen scavenging compositions which comprise a substituted or unsubstituted ethylenically unsaturated hydrocarbon and a transition metal catalyst. Inclusion of a photoinitiator or antioxidant in the scavenging composition is also preferred to facilitate and/or control the composition's scavenging properties. The method can be used for initiating scavenging in packaging layers or articles for oxygen sensitive products such as food and beverage.

Abstract:
The present application discloses a thermally conductive, electrically insulating film comprising: a thermoplastic resin accounting for 15-50% of the weight of the thermally conductive, electrically insulating film, and a thermally conductive filler accounting for 40-70% of the weight of the thermally conductive, electrically insulating film; wherein the thermally conductive filler comprises: a thermally conductive carbon-based filler, a thermally conductive metal oxide or hydroxide filler and a thermally conductive ceramic filler. The thermally conductive, electrically insulating film is used in electronic products or devices to not only impart excellent heat dissipation capability to electronic products and devices, but also meet the insulativity requirement for electronic products and devices. Meanwhile, such a thermally conductive, electrically insulating film further features excellent flame retardancy and mechanical properties to meet the requirements of the operating environment.
