ABSTRACT:
The invention relates to a process for sanitizing post-consumer wastepaper fibers for liquid packages and containers, a paper product for food packaging and a liquid food container. The process comprises providing paper fibers from a wastepaper recycle process, adding water to the paper fibers to achieve a slurry, de-watering the slurry to obtain a paper fiber stream and passing the fiber stream through a mixing device while heating the fiber stream and supplying hydrogen peroxide in the mixing device.
