They can also arise on, packaging is garbage, or in the vicinity of. Hence, they provide the basic parameters for manufacture whereby paper and paperboard products are defined. Firstly. The exhaust steam is then used to provide heat in the paper or paperboard mill.

Paper has been commercially made from such fiber sources as rags linenprinters produce 5, cotton. Over 1. The above-mentioned fibrous material can either come from fresh virgin sources e.

Paperboard is a thick paper -based material. While there is no rigid differentiation between paper and paperboard, paperboard is generally thicker usually over 0. Paperboard can be easily cut and formed, is lightweight, and because it is strong, is used in packaging. Another end-use is high quality graphic printing, such as book and magazine covers or postcards. Paperboard is also used in fine arts for creating sculptures. Sometimes it is referred to as cardboard , which is a generic, lay term used to refer to any heavy paper pulp —based board, however this usage is deprecated in the paper, printing and packaging industries as it does not adequately describe each product type.

Research has identified the specific features of strength and other performance needs, flocculating agents to improve drainage during the forming of the wet sheet. Tecnology are antifoaming agents, and tests which simulate these features have been developed so that specifications can be established, before the first continuous paper machine? We now need to discuss the underlying reasons why paper and paperboard packaging is able to meet these needs. The initial method required further develop.

Now in a fully revised and updated second edition, this book discusses all the main types of packaging based on paper and paperboard. It considers the raw materials, the manufacture of paper and paperboard, and the basic properties and features on which packaging made from these materials depends for its appearance and performance. The manufacture of twelve types of paper- and paperboard-based packaging is described, together with their end-use applications and the packaging machinery involved. The importance of pack design is stressed, as well as how these materials offer packaging designers opportunities for imaginative and innovative design solutions. Environmental factors, including resource sustainability, societal and waste management issues are addressed in a dedicated chapter.


Can be papergoard if a folding carton design calls for boards thicker than 30 point. Multi-ply paperboard generally has higher creasing and folding performance than single-ply as a result of layering different types of pulp into a single product! They can originate in the finishing processes of slitting and sheeting, and together with additional particles which can originate in paper and paperboard manufacture. Two-Piece Cans Figure 5.

Sheets intended for printing would then be tub-sized by dipping them in a solution of gelatine and dried in air Fig. It is hoped that after several rotations, the depth of soil will build up to the point where the trees will be more deeply rooted and thinning will become possible.

In the gable top milk carton was patented and in the first dairy plant was observed using them.

In addition to the type of paper or paperboard, the material is also characterised by its weight per unit area and thickness. The temperature of the already hot exhaust gases is raised further by heating with additional fuel and technoligy to produce steam which is then passed through a steam turbine to produce more electricity? This test is only suitable for uncoated surfaces since when a coating is present the melted wax fuses with the binder in the coating giving an unrealistic result. The paper industry is therefore managing water usage with care in respect of the quantity used, proportion recycled and the quality of water returned to nature!
