Tech students Maharanapratap College of Technology, Gwalior, [email protected] [email protected] [email protected] ABSTRACT Corrugated board is widely used in the packing industry. The main advantages are lightness, recyclability and low cost. This makes the material the best choice to produce containers devoted to the shipping of goods. Furthermore examples of structure design based on corrugated boards can be found in different fields. Structural analysis of paperboard components is a crucial topic in the design of containers. It is required to investigate their strength properties because they have to protect the goods contained from lateral crushing and compression loads due to stacking. However in this paper complete and detailed information are presented. Keywords: - corrugated boards, recyclability, compression loads. Smaller flutes offer printability advantages as well as I.

THE USE OF OLD CORRUGATED BOARD IN THE MANUFACTURE OF HIGH QUALITY WHITE PAPERS by Rene' H. Kapik A Thesis submitted in partial fulfillment of the course requirements for The Bachelor of Science Degree Western Michigan University Kalamazoo, Michigan December, 1983 ABSTRACT Clean corrugated board waste was fractionated into its softwood/ hardwood fiber components, repulped using a kraft pulping process, and bleached using a CEHD bleaching sequence in an effort to produce high brightness fiber suitable for use in medium to high quality white paper. The papers produced had almost equivalent mechanical strengths and opacity, but possessed unsatisfactory brightness and cleanliness when compared to commercially manufactured,:. bleached kraft pulps of identical softwood/hardwood contents. Based on this experimental data, the use of recycled fiber from corrugated board as a fiber substitute in the manufacture of high quality printing and writing papers is not recommended due to its inferior brightness and cleanliness.

  • Paper from Alternative Fibres the Facts
    Paper From Alternative Fibres The Facts The paper and paper packaging industry depend on an efficient, abundant and economically viable source of cellulose fibre to manufacture the huge variety of paper products we use today, like; newspapers, magazines, tissue, and paper packaging. Most commonly fibre is sourced from trees, a natural renewable and sustainable source but, cellulose can also come from other agricultural sources. What are ‘alternative fibres’? • Cotton and linen remain excellent papermaking fibres, with very high cellulose content. This gives superior The key ingredient in papermaking is cellulose, which is strength and a luxurious feel but comes at a higher cost. derived from the vegetable fibres found in trees and other plants.

  • Outlook for U.S. Paper and Paperboard Sector and Wood Fiber Supply in North America
    Chapter 5 - Outlook for U.S. paper and paperboard sector and Wood fiber supply in North America Mr. Peter J. Ince United States Forest Service U.S. Forest Products Laboratory, Madison, Wisconsin Abstract, Consumption of wood fiber in pulp, paper and paperboard increased in the United States over the past century and is projected to increase well into the next century at a decelerating rate of growth. Harvest of pulpwood on forest land is the single largest source of wood fiber, followed by recycled paper and wood residues. In the past decade, wood residues declined in supply while use of recycled paper increased rapidly. Use of recycled paper is projected to increase more steadily in the future with slower growth in paper recovery for recycling. Harvest of pulpwood on forest land is projected to remain the dominant source of U.S. fiber supply through the first half of the next century. Softwood pulpwood harvest on forest land is projected to increase as U.S. softwood residue supplies decline. Pulpwood stumpage values are projected to increase in the United States, based on supply and demand analysis, gradually improving economic opportunities for growing hardwood short-rotation woody crops on agricultural land. Hardwood pulpwood harvest on forest land is projected to increase for several decades but then decline in the long run with increasing fiber supply from agricultural short-rotation woody crops. Canada is projected to remain the principal source of U.S. pulp and paper imports, which are projected to increase. Most Canadian domestic pulpwood supply is projected to remain wood residues, as Canadian lumber production and residue output are projected to increase in the future.

  • Conservation of Coated and Specialty Papers
    RELACT HISTORY, TECHNOLOGY, AND TREATMENT OF SPECIALTY PAPERS FOUND IN ARCHIVES, LIBRARIES AND MUSEUMS: TRACING AND PIGMENT-COATED PAPERS By Dianne van der Reyden (Revised from the following publications: Pigment-coated papers I & II: history and technology / van der Reyden, Dianne; Mosier, Erika; Baker, Mary , In: Triennial meeting (10th), Washington, DC, 22-27 August 1993: preprints / Paris: ICOM , 1993, and Effects of aging and solvent treatments on some properties of contemporary tracing papers / van der Reyden, Dianne; Hofmann, Christa; Baker, Mary, In: Journal of the American Institute for Conservation, 1993) ABSTRACT Museums, libraries, and archives contain large collections of pigment-coated and tracing papers. These papers are produced by specially formulated compositions and manufacturing procedures that make them particularly vulnerable to damage as well as reactive to solvents used in conservation treatments. In order to evaluate the effects of solvents on such papers, several research projects were designed to consider the variables of paper composition, properties, and aging, as well as type of solvent and technique of solvent application. This paper summarizes findings for materials characterization, degradative effects of aging, and some effects of solvents used for stain reduction, and humidification and flattening, of pigment-coated and modern tracing papers. Pigment-coated papers have been used, virtually since the beginning of papermaking history, for their special properties of gloss and brightness. These properties, however, may render coated papers more susceptible to certain types of damage (surface marring, embedded grime, and stains) and more reactive to certain conservation treatments. Several research projects have been undertaken to characterize paper coating compositions (by SEM/EDS and FTIR) and appearance properties (by SEM imaging of surface structure and quantitative measurements of color and gloss) in order to evaluate changes that might occur following application of solvents used in conservation treatments.

Green l'olp and Paper Research Institute of Canada, Pointe Claire, P.Q., H9H 359 CANADA (Received 22 September 1975) ABSTRACT The dimensions of the fibres in oven-dry blocks of mood from three species (white spruce, 1)ouglas-fir, and larch) were deduced from measure~ilentsof bulk density and the number of fibres per unit cross-sectional area. The blocks \\.ere then cooked Ly the soda process to various yields, and the fibre dimensions were redeterlined after the blocks had been washed and oven-dried. The weight of the fibres per unit length decreased almost in proportion to the yield loss, I~eingreduced at 40% yield to 42% of its value in wood. This finding indicates that the fibres were shortened to only a small extent by pulping (ca. 4% at 40% yield) and that the major changes were in the transverse dimensions of the fibres. At 40%, yield, cell-wall thickness and fibre width were respectively rechlced to 52.5% and 84% of their original values. The results were independent of wood. species.

  • Cellulose Was Discovered in 1838 by the French Chemist Anselme Payen, Who Isolated It from Plant Matter and Determined Its Chemical Formula
    Cellulose structure： The history of cellulose： Cellulose was discovered in 1838 by the French chemist Anselme Payen, who isolated it from plant matter and determined its chemical formula. Cellulose was used to produce the first successful thermoplastic polymer, celluloid, by Hyatt Manufacturing Company in 1870. Production of rayon ("artificial silk") from cellulose began in the 1890s and cellophane was invented in 1912. Hermann Staudinger determined the polymer structure of cellulose in 1920. The compound was first chemically synthesized (without the use of any biologically derived enzymes) in 1992, by Kobayashi and Shoda How it is synthesized commercially or biologically： Cellulose is a source of energy for several types of microbes. Large amounts of cellulose is degraded to glucose by both bacterial and fungal microbes. The glucose derived from cellulose degradation is then used by other microbes as a carbon source to produce energy. Many fungi, specifically the members of Basidiomycetes perform critical ecological function by degrading cellulose present in decaying wood. Some animals can digest cellulose. When an herbivore, say a cow, consumes a plant, like grass, bacteria in their intestinal tract are able to break down the cellulose into smaller parts that the cow's own digestive system can absorb. Some bacteria can actually produce their own cellulose, making a kind of film. The acetic acid bacteria used in the production of wine and beers is one of these types. The synthesized cellulose forms a film around the bacterial cell and becomes a kind of matrix, called a pellicle, which helps the acetic acid bacteria to float on the surface and access oxygen needed for their survival.
