  1. 1. Mechanics of paper webs in printing press applications

    Author : Artem Kulachenko; Sören Östlund; Thomas Abrahamsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Travelling webs; skew tension profiles; mixed dynamic formulation; fluting; Other engineering mechanics; Övrig teknisk mekanik;

    Abstract : The mechanics of paper is a difficult subject because paper is a unique material. It is very thin, flexible at bending, unstable in compression and stiff at tension. Dealing with paper we have to account for orthotropy and heterogeneities created during the manufacturing process. READ MORE

  2. 2. Flexographic Post-Printing of Corrugated Board : Contact Mechanics and Print Quality

    Author : Erik Hallberg Hofstrand; Magnus Lestelius; Peter Rättö; Astrid Odeberg Glasenapp; D. Steven Keller; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flexography; Corrugated board; Post-printing; Contact mechanics; Print quality; Chemical engineering; Kemiteknik; Chemical Engineering; Kemiteknik;

    Abstract : As the corrugated board industry strives to produce products with a higher print quality in the converting stage, there is a need for a greater understanding of the factors influencing the final print quality and how we perceive the print. In this work, a method for quantifying the print quality of printed corrugated board is presented as well as methods that quantitatively characterize the mechanical interaction between the printing form and the corrugated board in the printing nip.

  3. 3. Nonlinear Creep Model of Paper and Corrugated Board Materials

    Author : Poorvi Patel; Teknisk logistik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technological sciences; Finite element modeling; Creep-recovery tests; Schapery creep equation; Localbuckling; Orthotropic materials; Teknik;

    Abstract : Models of the nonlinear creep behavior of paper, and of the global buckling , local buckling and creep buckling of corrugated board have been developed. The studies of creep and buckling were limited to climate conditions with constant relative humidity. First the short-term elastic buckling of corrugated board panels was studied. READ MORE

  4. 4. Strategies for improving kraftliner pulp properties

    Author : Stefan Antonsson; Mikael E. Lindström; Gunnar Henriksson; Mats Johansson; Hans Theliander; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lignin; xylan; kraftliner pulp; mechano-sorptive creep; hygroexpansion; stiffness; fibre shape; fibre width; lignin; xylan; kraftlinermassa; mekanosorptivt kryp; hygroexpansion; styvhet; fiberform; fiberbredd; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Abstract : A large part of the world paper manufacturing consists of production of corrugated board components, kraftliner and fluting, that are used in many different types of corrugated boxes. Because these boxes are stored and transported, they are often subjected to changes in relative humidity. READ MORE

  5. 5. Basic Testing and Strength Design of Corrugated Board and Containers

    Author : Tomas Nordstrand; Byggnadsmekanik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material technology; Materiallära; materialteknik; Produktteknik allmän ; Technology of other products; corrugation; compression; collapse; buckling; bending; box;

    Abstract : Packaging serves a lot of purposes, and would be hard to do without. Packaging protects the goods during transport, saves costs, informs about the product, and extends its durability. A transport package is required to be strong and lightweight in order to be cost effective. READ MORE
