Title
(EN) ACTIVE MASTERBATCH USING STEARATE AND AN OXIDIZABLE RESIN CARRIER
(FR) MELANGE MAITRE ACTIF A STEARATE ET SUPPORT OXYDABLE
Abstract
(EN)
Herein is disclosed a masterbatch of cobalt stearate with an oxidizable resin, preferably comprising cyclohexenyl methyl acrylate, such as ethylene/methyl acrylate/cyclohexenyl methal acrylate terpolymer (EMCM). Preferable, the cobalt stearate and the resin are compounded together. Also disclosed are a method for preparing the masterbatch, preferably by compounding the cobalt stearate and the resin, and a method for making an oxygen scavenging packaging article. The packaging article is made by providing the masterbatch and a composition comprising a second oxidizable resin, which may be the same as is found in the masterbatch. The masterbatch and the composition are blended and the bland formed into the packaging article. The packaging article can be single layer multilayer, and flexible or rigid.
(FR)
L'invention concerne un mélange maître à base de stéarate de cobalt et de résine oxydable, comprenant de préférence un terpolymère cyclohexényl méthyl acrylate, du type éthylène/méthyl acrylate/cyclohexényl méthal acrylate. De préférence, le stéarate de cobalt et la résine sont mélangés. L'invention concerne également un procédé relatif à l'élaboration du mélange maître, de préférence par mélange des deux substances considérées, et un procédé relatif à l'élaboration d'article d'emballage désoxygénant. A cet effet, on fournit le mélange maître et une composition renfermant une seconde résine oxydable, pouvant être la même que dans le mélange maître. Le mélange maître et la composition sont mélangés, et le mélange résultant est mis en forme comme article d'emballage, lequel peut être monocouche ou multicouche, et flexible ou rigide.
