Title
(EN) POLYOLEFIN COMPOSITIONS WITH IMPROVED OXYGEN SCAVENGING CAPABILITY
(FR) COMPOSITIONS DE POLYOLÉFINE AYANT UNE CAPACITÉ DE PIÉGEAGE D'OXYGÈNE AMÉLIORÉE
Abstract
(EN)
Oxygen scavenging polymeric compositions that possess an improved oxygen scavenging capability and can be formed into transparent / translucent thin films are disclosed. A composition can include iron powder, ferrous sulfate heptahydrate (FeSO4.7H2O) and glycerol dispersed in polyethylene. Such compositions are useful for creating packaging films with improved oxygen scavenging capability.

L'invention concerne des compositions polymères piégeant l'oxygène qui possèdent une capacité de piégeage d'oxygène améliorée et peuvent adopter une forme de films minces transparents/translucides. Une composition peut comprendre de la poudre de fer, du sulfate ferreux heptahydraté (FeSO4.7H2O) et du glycérol dispersé dans du polyéthylène. De telles compositions sont utiles pour créer des films d'emballage ayant une capacité de piégeage d'oxygène améliorée.
