Title: (DE) SAUERSTOFFABSORBER BESCHLEUNIGER
(EN) OXYGEN SCAVENGER ACCELERATOR
(FR) ACCELERATEUR D'ABSORPTION D'OXYGENE
Abstract: front page image
(EN) An iron-based oxygen scavenging packet is set forth in which the rate of uptake of oxygen is increased by virtue of the presence of an oxygen uptake accelerator such as water which is introduced into the packet. Methods of increasing the rate of oxygen absorption by the iron-based oxygen scavenging packet are also set forth.
(FR) L'invention porte sur un emballage comportant un désoxygénant à base de fer dans lequel le taux d'absorption de l'oxygène est renforcé par la présence d'un accélérateur d'absorption tel que de l'eau introduit dans l'emballage. L'invention porte également sur les procédés associés de renforcement du taux d'absorption de l'oxygène dans de tels emballages.
