TECHNICAL MANUAL I 03 INTRODUCTION HOW DOES IDEM WORK? FIGURE 1 An IDEM copy is the reaction of two separate coatings under pressure (from a pen, impact CB printer, etc). One coating, CB (or coated back) consists of pressure sensitive microcapsules, containing colourless dyes known as colourformers, dissolved in an oil. Under pressure, these capsules rupture, releasing the dyes, which are then absorbed by the second coating, CF (or coated front). #e CF coating is a highly absorbent coating, which transforms the colourformers into a sharp, intense image. There are 3 grades of IDEM paper: FIGURE 2 CB #e original or top sheet of a multi-part form with a reverse-side, CFB pressure sensitive coating, which transfers an image. CFB #e pressure sensitive intermediate sheet(s) of a multi-part form, which both receives and transfers an image (the most sensitive sheet).

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.

  • 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.

  • 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.

CHANGES IN PRINT PAPER DURING THE 19TH CENTURY AJ Valente, ([email protected]), President, Paper Antiquities When the first paper mill in America, the Rittenhouse Mill, was built, Western European nations and city-states had been making paper from linen rags for nearly five hundred years. In a poem written about the Rittenhouse Mill in 1696 by John Holme it is said, “Kind friend, when they old shift is rent, Let it to the paper mill be sent.” Today we look back and can’t remember a time when paper wasn’t made from wood-pulp. Seems that somewhere along the way everything changed, and in that respect the 19th Century holds a unique place in history. The basic kinds of paper made during the 1800s were rag, straw, manila, and wood pulp.

  • 1 Fibre Box Handbook Glossary Adhesive
    Fibre Box Handbook Glossary A Adhesive: Substance capable of adhering one surface to another. For fiberboard boxes, the substance is used to hold plies of solid fiberboard together, to hold linerboard to the tips of flutes of corrugated medium, or to hold overlapping flaps together to form the joint or to close a box. Anilox System: Inking system used in flexographic presses. B Bale: A shaped unit, usually containing compressible articles or materials, enclosed in a fiberboard container not conforming to the carriers’ rules for a box, or enclosed in other wrapping, and bound by strapping, rope or wire under tension. Banded Unit: A package or palletized load that has a band or bands (usually plastic) applied to it. Bar Code: An identification symbol. Alpha or alpha-numeric information is encoded in a sequence of high-contrast, rectangular bars and blank spaces. The relative widths of these bars and spaces and their sequence differentiate the individual characters that make up the encoded information. Bar codes are “read” by electronic scanners. Basis Weight (of Containerboard): Weight of linerboard or corrugating medium expressed in terms of pounds per 1,000 square feet (msf). Bending: In the expression "proper bending qualities," the ability of containerboard or combined board to be folded along score lines without rupture of the surface fibers to the point of seriously weakening the structure. Blank or Box Blank: A flat sheet of corrugated or solid fiberboard that has been cut, slotted and scored so that, when folded along the score lines and joined, it will take the form of a box.

  • Handmade Paper: a Review of Its History, Craft, and Science
    REVIEW ARTICLE bioresources.com HANDMADE PAPER: A REVIEW OF ITS HISTORY, CRAFT, AND SCIENCE Martin A. Hubbe a* and Cindy Bowden b For over 2000 years the manual craft of papermaking has been practiced all over the world utilizing a variety of techniques. This review describes the evolution of hand papermaking and its cultural significance. Paper’s evolution has been shaped by the structure and chemical composition of the fibers. Almost every aspect of modern papermaking technology has been foreshadowed by traditional practices. Such practices were passed down for many generations within families of papermakers. The main sources of cellulosic fiber evolved as the ancient craft migrated from its birthplace in China to Korea and Japan, the Islamic world, and then to Europe and America. Though most paper made today comes from automated, continuous production systems, handmade paper has enjoyed a resurgence, both as a traditional craft and as an art-form. In addition, traditional papermaking methods can provide insights to help in modern applications involving cellulosic fibers.

  • Paper & Cardboard
    Paper & cardboard Exam expectations Knowledge about materials is always tested in the written paper. You are expected to know about paper/card and at least one other material area. Know about paper/card • Where it comes from • How it is made • How products are cut from paper/card Materials and components • In what stock sizes and forms is paper/board supplied? • Is it a renewable/non-renewable material? • How are papers and cardboards classified (grouped)? • What properties do different papers/boards have? • What are components and why are they used? • What are combined materials? Standard stock forms Most materials are supplied in standard stock forms. When specifying paper and cardboard you would choose the size (A1, A2, A3, A4 etc.) then you would choose the weight (grams per square metre). It is usually best to use standard stock forms: • The printing industry need consistent sizes and qualities • Makes it cheaper to buy in this form • Non-standard can greatly increase the costs Paper • Paper is a web-like material made from very fine vegetable fibres. • These fibres usually come from wood pulp although sometimes plants such as flax and hemp are used. • The fibres are made of cellulose and they stick to each other to form a strong web • Recycled fibres are often mixed with new or “virgin” materials Making Paper Papermaking has been around for 2,000 years although it is now highly automated Boiled up to make wood pulp Trees cut & Water added shredded Chemicals and dyes added Pulp poured over fine mesh and squeezed between rollers Fibres • When plants are used to make paper, it is usually necessary to use a special chemical process to break down the lignin found inside the cell walls of the plant.
