    Sammanfattning : Food packaging should ensure the safety and quality of food, minimize spoilage and provide an easy way of storing and handling it. Barrier coatings are generally used to meet the demands placed on fibre-based food packages, as these have the ability to regulate the amount of gases that can enter them. LÄS MER

  3. 12. Effects of Citric Acid on Starch-Based Barrier Coatings

    Författare :Erik Olsson; Lars Järnström; Caisa Johansson; Julien Bras; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Starch; Citric acid; Cross-linking; hydrolysis; Montmorillonite; WVTR; OTR; Barrier properties; Chemical Engineering; Kemiteknik;

    Sammanfattning : With growing environmental concerns, efforts are made to replace petroleum based products with renewable alternatives. This is particularly evident in the packaging industry, where replacing synthetic polymers with renewable materials is of considerable interest. LÄS MER

  4. 13. Variations Related to Print Mottle in Starch-Containing Paper Coatings

    Författare :Micael Ragnarsson; Lars Järnström; Gunnar Engström; Martti Toivakka; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pigment coating; porosity variations; coating structure; coat weight variations; starch; dextrin; CMC; latex; print mottle; calendering; pilot coating; offset printing; Chemical Engineering; Kemiteknik;

    Sammanfattning : Starch in paper coatings is known to increase the risk of print mottle in lithographic offset printing. The objective of this study was to increase the understanding of this behaviour. LÄS MER
