Pulp and Paper


Metra Martech work in the Pulp and Paper industry started with work on sizing for a Swedish Chemical company in the mid-1970s. This was followed by a joint venture project on paper chemicals with the (then) BIS company.

Since then a large variety of work has been carried out for clients. This has covered subjects such as:

  • Change in technology in the process:
      - neutral sizing
      - demand for long life paper (archives)
      - chlorine free bleaching
  • User technology changes (printing, packaging, etc.)
  • Environment (recycling waste etc.), and
  • Customer satisfaction at the level of:
      - pulp buyer
      - merchant
      - converter, and
      - end user.

    Paper studies have included, for example, kraftliner, printings and writings, corrugated, specially coated and impregnated paper, magazine paper and newsprint.


    Peripheral studies have examined:
    • trends in distribution (related to the need for corrugated cases)
    • retail display (related to the use of trays, display packs, etc)
    • competitiveness in packaging
    • development of offset litho
    • laser printing
    • the future of newspaper readership
    • various studies on pumps, filters, maintenance systems etc.
