  1. 1. Barrier properties of greaseproof paper

    Detta är en avhandling från Institutionen för kemi

    Författare :Henrik Kjellgren; Karlstads universitet.; [2005]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Chemical engineering; TEKNIKVETENSKAP Kemiteknik; Chemical Engineering; Kemiteknik; Greaseproof papers; Air permeance; Coatings; Chitosan; Oxygen Barrier properties;

    Sammanfattning : The barrier properties of greaseproof paper are achieved by extensive beating of the fibres. This treatment results in high costs for energy, both as beating energy and drying energy. A full-scale trial has been performed to investigate the role of the pulp with respect to energy demand and the barrier properties of the final papers. LÄS MER

  2. 2. Influence of paper properties and polymer coatings on barrier properties of greaseproof paper

    Detta är en avhandling från Karlstad : Karlstads universitet

    Författare :Henrik Kjellgren; Karlstads universitet.; [2007]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Chemical engineering; TEKNIKVETENSKAP Kemiteknik; Chemical Engineering; Kemiteknik; Greaseproof paper; Barrier properties; Gas barrier; Paper properties; Coatings;

    Sammanfattning : Greaseproof paper has a dense structure and therefore provides a natural barrier against materials like fat and oils. The barrier is obtained by extensive refining of the pulp. LÄS MER
