Summary
Mondi is a truly innovative company and launched several types of recyclable paperbased films which replace polymerbased packaging for stretch films and bio garbage bags. Goals: -Cover and modify the paper fibers to improve the barrier properties and reduce the sensitivity against moisture by 30%. -Achieve a longterm hydrophobic sizing of paper at low pH values by combining natural and synthetic additives -Find chemical additives that are food compliant. -Enable Mrs. Esteves experience to perform a mill trial on an industrial papermachine and renew the bilateral know how exchange between RISE/Mondi for future projects. A n. of promising novel technologies will be developed to radically transform the paper properties in contact with water vapor and liquids at different pH.The technologies will be evaluated in the lab by evaluating the sheets properties.To obtain valid results a statistical trial plan with repetitions will be employed.The properties will be compared with ref. sheets.The promising technologies/modifications will be identified/evaluated in a mill trial to assess how the modification affects the paper machine runnability and how the “real” ind. produced paper compares to the lab.Mondi expects a more conclusive view on the effect of new chemical additives interaction with water/vapor and fibers in paper.The results will enable to develop next paper grades and be ahead of the Central Europe and South America competition by its renewed RISE partnership.
Populärvetenskaplig beskrivning
Thanks to the biobased raw materials such as wood fibers, paper will replace plastic in applications not only for shopping bags. For the use in garbage bags, a number of novel technologies will be developed based on biobased chemistry and fiber treatment, with the potential to radically improve paper quality and extend the usability of the bags in kitchens of Sweden.
