AMORPHOUS SILICA IN PACKAGING FILM

摘要

An article of manufacture includes an oxygen scavenger and an amorphous silica. The article can be in the form of e.g. a film or sealing compound. A package can be made from the article for containing an oxygen-sensitive article such as food. The amorphous silica reduces migration of odor causing by-products of the oxygen scavenging process. A method of making an article of manufacture having reduced migration of by-products of an oxygen scavenging reaction includes providing an article including an oxygen scavenger and an amorphous silica; and exposing the article to actinic radiation.
