ABSTRACT:
A film, laminated product, and other packaging materials are disclosed, each including an oxygen scavenger composition including mer units derived from a substituted alicyclic compound having non-aromatic, ethylenic functionality, mer units including an ionomeric group, and mer units of a di- or polyfunctional hydrocarbon compound. Certain oxygen scavenger compositions have been found to act as an oxygen scavenger under both ambient and refrigeration conditions, to be compatible with conventional film forming packaging materials, to inhibit undesirable oligomer formation and oxidation by-product formation, and to be readily formable and processable using conventional film forming equipment.
