MANUFACTURE OF PAPER AND PAPERBOARD
2001A process of making paper or paper board comprising forming a cellulosic suspension, flocculating the suspension, draining the suspension on a screen to form a sheet and then drying the sheet, characterised in that the suspension is flocculated using a flocculation system comprising a clay and an anionic branched water soluble polymer that has been ...

Numerical Investigation of Paperboard Forming
Nordic Pulp & Paper Research Journal, 2012Abstract A three dimensional numerical investigation of a commercial four-ply paperboard formed into a pear-shaped mould was presented. The numerical investigation included the effect of pressure, boundary conditions, material properties and different deformation and damage mechanisms such as delamination and plasticity. Simulations were

Packaging Technology and Science, 2014
Paper and paperboard are widely used in various types of packaging. Paper-based packaging is a recyclable, biodegradable, renewable and sustainable product, which gives it certain advantages over most plastic-based packaging materials. Although paper-based packaging, in some areas, lacks attractiveness in terms of visual appearance, 3D forming is an ...

Renal Cell Cancer among Paperboard Printing Workers
Epidemiology, 1992A physician's alert prompted us to investigate workers' cancer risk at a paperboard printing manufacturer. We conducted a retrospective cohort mortality study of all 2,050 persons who had worked at the facility for more than 1 day, calculated standardized incidence ratios (SIRs) for bladder and renal cell cancer, and conducted a nested case-control ...

This research work presents recent results on the formability of paper-based materials. Different kinds of commercial paperboard samples were evaluated using a laboratory 2D - formability tester, and a 3D deep-drawing equipment. It was found that the appearance of the formed shapes and the performance of paperboard in the forming process have a ...

Tensorial strength analysis of paperboard
Experimental Mechanics, 1985Tensorial-type failure criteria with linear and quadratic terms are used to calculate the strength of paperboard under plane stress. Theoretical predictions and experimental data are correlated in all four quadrants of biaxial normal stress with various levels of shear.

Bending stiffness loss of paperboard at conversion — predicting the bending ability of paperboard
Packaging Technology and Science, 1998The ability of paperboard to resist bending has been investigated. Paperboard is often bent in converting and packaging machines. The paperboard is bent over rolls and thus formed to certain curvatures. If the roll diameter is small the paperboard will be highly curved. This means that high tensile stresses occur on the convex side and high compression

Thin honeycomb paperboard(THPB) is an emerging carton material instead of corrugated paperboard(CPB) recently, public research results and comparative data have not yet found at present. CPB of flute A is selected as contrast material in the paper since its thickness and density are similar to THPB, then properties of two kinds of paperboard are ...
