摘要：
A multilayer active oxygen barrier film includes at least one bulk layer and a microlayer section including a plurality of microlayers, at least one of which includes an active oxygen barrier. The microlayer section can comprise at least one microlayer comprising an active oxygen barrier, and at least one microlayer comprising a passive oxygen barrier. A method of making a multilayer active oxygen barrier film is also disclosed, in which a bulk layer is extruded, a plurality of microlayers is coextruded to form a microlayer section; and said bulk layer and said microlayer section are merged to form a multilayer film and wherein the plurality of microlayers includes an active oxygen barrier.
