Kaushal1, V.K.Sirohiya2 and R.K.Rathore3 1 2 Assistant Prof. Mechanical Engineering Department, Gwalior Institute of Information Technology,Gwalior, Assistant Prof. Mechanical Engineering 3 Departments, Gwalior Engineering College, Gwalior, M. 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. INTRODUCTION structural advantages for retail packaging. Corrugated board is essentially a paper sandwich consisting of corrugated medium layered between inside II. HISTORY and outside linerboard.

  • Making Paper from Trees
    Making Paper from Trees Forest Service U.S. Department of Agriculture FS-2 MAKING PAPER FROM TREES Paper has been a key factor in the progress of civilization, especially during the past 100 years. Paper is indispensable in our daily life for many purposes. It conveys a fantastic variety and volume of messages and information of all kinds via its use in printing and writing-personal and business letters, newspapers, pamphlets, posters, magazines, mail order catalogs, telephone directories, comic books, school books, novels, etc. It is difficult to imagine the modern world without paper. Paper is used to wrap packages. It is also used to make containers for shipping goods ranging from food and drugs to clothing and machinery. We use it as wrappers or containers for milk, ice cream, bread, butter, meat, fruits, cereals, vegetables, potato chips, and candy; to carry our food and department store purchases home in; for paper towels, cellophane, paper handkerchiefs and sanitary tissues; for our notebooks, coloring books, blotting paper, memo pads, holiday greeting and other “special occasion’’ cards, playing cards, library index cards; for the toy hats, crepe paper decorations, paper napkins, paper cups, plates, spoons, and forks for our parties. Paper is used in building our homes and schools-in the form of roofing paper, and as paperboard- heavy, compressed product made from wood pulp-which is used for walls and partitions, and in such products as furniture. Paper is also used in linerboard, “cardboard,” and similar containers. Wood pulp is the principal fibrous raw material from which paper is made, and over half of the wood cut in this country winds up in some form of paper products.

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.

  • Recycling Evaluation of Newly Developed Environmentally Benign Pressure Sensitive Adhesive for Postage Applications
    Recycling Evaluation of Newly Developed Environmentally Benign Pressure Sensitive Adhesive for Postage Applications Said Abubakr USDA Forest Service Forest Products Laboratory Madison, Wisconsin, USA Joe Peng United States Postal Service Washington, DC, USA Abstract The main objective of the United States Postal Service’s (USPS) program for environmentally benign pressure sensitive adhesive (PSA) is to develop postage stamp adhesives that do not adversely affect the environment. The goal is to develop PSA stamp products that can be successfully recycled into fine paper products in a typical recycling facility. This paper describes the development of the final specification and approved product list for PSA stamp production. Environmentally benign PSAs are a form of adhesive that places no significant additional burden on plants that are using recycled fiber. As a result of an initiative by the USPS, a team has been working cooperatively to help solve the problem of PSAs not being recyclable in recovered paper. The team consists of the USPS; the USDA Forest Service, Forest Products Laboratory (FPL); Springborn Testing and Research (STR); and industry representatives. Industry members include papermakers, paper recyclers, paper collectors, equipment manufacturers, and adhesive and chemical suppliers. The team’s goal is to work with industry to develop environmentally benign PSAs for postal applications that will fulfill both USPS specifications and be compatible with the USPS environmental strategic plan and will place no additional burdens on plants that use recycled fiber. In 1995, the USPS sponsored a conference to which the adhesive industry was invited to participate in the USPS Environmentally Benign Pressure Sensitive Adhesives for Postage Stamp Applications Program.

  • Resin Profile in a Bleached Kraft Pulp Process
    Resin Profile in a Bleached Kraft Pulp Process Jennie Berglund May 2012 Degree Project in Polymeric Materials, First Level Department of Fibre and Polymer Technology Royal Institute of Technology Stockholm, Sweden Abstract The aim with this project was to investigate how the amount and composition of resins varied during the process producing bleached birch pulp at the mill SCA Packaging Munksund. A literature study about how the resin removal can be improved has also been included. Problems with resins in the process are common at pulp and paper mills, especially when birch is used as a raw material. The resin can cause deposits on the equipment leading to process stops, but also lowered mechanical properties and spots on the paper products. The addition of tall oil to the digester is one way of improving the removal of resins, seasoning of wood, and a good debarking are other ones. Also the different washing and bleaching steps can affect the amount of resin remaining in the pulp. In this study pulp samples from eight different positions in the process were analyzed. To extract the samples a Soxtec device was used. Results showed that the most effective resin removal happened during the washing in their first washing step after the digester, a DD-washer. Here 77 % of the resin was removed, of totally 88 % during the whole process. Another step which was effective was the final washing step, the PO-press. About 36 % of the remaining resins in the pulp which entered the PO-press were washed out here. The extracts were analyzed with GC-FID and GC-MS to identify and quantify the substances, and determine how the composition varied over the manufacturing process.

  • 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.
