Claims15
A material suitable for use in packages comprising nano-sized cellulose and an ethylene scavenging and/or ethylene absorbing agent.
A process for producing a dispersion comprising microfibrillated cellulose and an ethylene scavenging or ethylene absorbing agent wherein the process comprises the steps:
- a) providing a slurry comprising cellulosic fibers,
- b) adding an ethylene scavenging or ethylene absorbing agent to the slurry and treating the slurry by mechanical disintegration so that a dispersion comprising microfibrillated cellulose is formed in which the ethylene scavenging or ethylene absorbing agent is being absorbed to the surface of the microfibrillated cellulose.
A dispersion comprising microfibrillated cellulose and an ethylene scavenging or ethylene absorbing agent, in which the ethylene scavenging or ethylene absorbing agent is absorbed to the surface of the microfibrillated cellulose.
